Got a Treadmill? Got Speedwork!

Many runners at some point will find themselves in a rut. They’ve stagnated. Same mileage at the same intensity, week after week. They may even be putting on a few pounds even though they’re running. So, what’s up?

Well, the better question to ask might be “What’s not up?” Once you’ve become an established runner, it doesn’t take long for your body to acclimate to the demands you’re putting upon it. So, while that 5-miler you do every Monday, Wednesday, and Friday may be providing you some good base mileage and an aerobic workout, it’s probably not doing much to help make you faster, fitter, stronger. Nor is it doing much to ramp up your metabolism, the key in keeping those pounds off.

What’s the answer? SPEEDWORK! One weekly interval workout will do wonders to jack up your metabolism helping to shed those few pounds. It will also help increase your VO2Max, which is your body’s ability take in and use oxygen at the muscle level where it’s used to make energy. That weekly interval workout will also help push out your lactate threshold. Lactate is a byproduct of energy production. Ever get that burning sensation in your legs when you speed up and run hard? That’s due to lactate buildup. Usually the body is able to clear it out of the blood and there’s no problem. But when you ramp-up speed or intensity too quickly, the lactate can build up quicker than the body is able to clear it out of the bloodstream. Exposing your body to faster runs can gradually push out that lactate threshold, so it will take longer before you feel that burn.

So, I know some of you are saying, “I’d love to add speed work, but I don’t live near a track.” Well, if you own a treadmill, have a membership to a gym with treadmills, or have friend or family member with a treadmill, then you can get in an awesome interval workout.

An interval is nothing more than running fast for a certain distance and then running slow for the same distance or for a specific time. Typically a short interval (like a 200m interval) is run at a pace that’s about 30 seconds slower than your 5K race pace. Longer intervals (like the 800m or 1200m) are typically run at 30 seconds slower than you 10K race pace.

Does the math to figure out the pace for such a short distance make your brain hurt? Don’t worry. I’m with you. Put that calculator down and use The McMillan Running Calculator instead. Simply select the distance (5K or 10K) and then put in your race time and hit “calculate.” The next screen will tell you paces for every training distance you’d ever need to know based on your 5K or 10K pace.

Most interval workouts use some combination of 200m, 400m, 600m, 800m, 1000m, and 1200m intervals. Each fast interval is followed by a slow recovery interval. The recovery interval isn’t based on a certain distance. It’s based on time. The shorter the fast interval distance, the shorter the recovery interval time. The longer the fast interval distance, the longer the recovery interval time. For example, a runner doing a 6x800m workout would take about a 90-second recovery interval jog/walk between each fast 600m interval. A runner doing a 4x1600m workout would take about a 3-minute recovery interval jog/walk between each fast 1600m interval.

Most treadmills have an oval track diagram on the control display providing a wonderful visual to track your progress as you run your intervals. If you’ve never run intervals on a track you may not be familiar with the typical interval distances. The key below can help you better understand the distances you’re running as you’re looking at the track display on your treadmill monitor.

• 200m = 1/2 lap (1/8 mile on the treadmill)
• 400m = 1 lap (1/4 mile on the treadmill)
• 800m = 2 laps (1/2 mile on the treadmill)
• 1000m = 2.5 laps (5/8 mile on the treadmill)
• 1200m = 3 laps (3/4 mile on the treadmill)
• 1600m = 4 laps (1 mile on the treadmill)

Your body can acclimate to intervals just like it does when running that same old 5-miler three times a week. So, mix-up your interval workouts. Keep your body guessing by varying the interval distances each week. There’s no right or wrong way. Just remember to insert a recovery interval in between each fast interval. Below are some sample workouts for you to incorporate once a week into your normal running routine. 
  • Workout #1—5x1000m @5K race pace with 2-minute recovery (walk or jog) in between
  • Workout #2—6x800m @10K race pace with 90-second recovery (walk or jog) in between
  • Workout #3—Do Three sets of the following:  1x1200m @ 10K race pace with 1-minute recovery, 1x400m @5K race pace with a 3-minute recovery (walk or jog) before repeating the set
  • Workout#4—4x1600m @10K race pace with 3-minute recovery (walk or jog) in between
  • Workout#5—8x800m @10K race pace with 90-second recovery (walk or jog) in between
  • Workout#6—400m @ 5K race pace (30sec recovery); 800 @ 10K race pace (90-sec recovery); 1200m @10K race pace (2-min recovery); 1600m @10K race pace (3-min recovery); 1200m @10K race pace (2-min recovery); 800 @ 10K race pace (90-sec recovery); 400m @ 5K race pace

Your total mileage for an interval workout may be no more than 3-4 miles, but you’re getting a lot more out of this workout than your regular 5-miler. Think of the interval workout as a “Quality Workout.”

To better simulate outside running, be sure to set your treadmill to an incline of 1° or 2°. This will help account for uneven terrain of outside running.

The 5K Race: Simple and Effective Training Tips

The 5K race. Many runners have a love hate relationship with this distance. On the one hand, it's a short race. If you're not too concerned with time, then most anyone with a basic fitness level can run or run/walk the distance. On the other hand, however, if you're racing it, it can be a grueling distance.

To race a 5K, you're pretty much in high gear the entire race. There's very little ramp-up time and very little room for any back-sliding. That however, is what appeals to many runners. They love the rush of adreniline and challenge that a 5K provides.

So how do you train for a 5K? There are a lot of different theories on training for a 5K, but the one common thread of most 5K training plans is speed work. I personally think that three types of runs are key to 5K training—Lactate Threshold Runs, Aerobic Power Runs, and Endurance Runs.

Lactate Threshold Runs are more commonly known as Tempo runs. Lactate has gotten a pretty bad rap over the years. Ever feel that deep down burning sensation in your legs when you've pushed the intensity of a run? That's due to the buildup of blood lactate (a waste product of the energy production). Because you've ramped up the intensity so quickly, the body isn't able to clear it out of the blood stream fast enough, so you feel a burning sensation and you begin to fatigue and slow down. What many runners don't know is that lactate can actually be used as a source of muscle fuel. The key is pushing out that lactate threshold. In other words pushing out the point at which you feel the burn. A great way to do that is through tempo runs. These are runs in which you run about 30seconds slower than your 10K race or at about 80-90% of your Max Heart Rate. So, it's a slightly uncomfortable run, but not a run where you're completely wiped-out at the end.

Typically a tempo run begins with a slow mile and then you pick it up to your tempo pace for a certain distance and then pull it back down to a slow pace again for the last mile. For example, in a 4-mile tempo run, you’ll run a slow 1-mile warm-up, 2 miles at tempo pace, and then a slow 1-mile cool-down.

Aerobic Power Runs are another great training tactic to help build speed as well as increase your body's ability to take in more oxygen that's utilized at the muscle level for energy production. Aerobic Power Runs are typically run as intervals on a track. The intervals are fast and usually run at 90% of your Max Heart Rate. Each interval is followed by an equal distance slow interval or equal time but slow interval. For example if you run a 3:30 800m, then you'd either slow-jog or walk another 800 or you'd slow-jog or walk for 3minutes 30 seconds. Typically, I recommend the same-distance-slow-recovery-interval for someone new to intervals. For a more experienced runner, I'd recommend the same-time-slow-recovery-interval. Running at this high intensity level with recovery intervals in between, helps your body's ability to take in more oxygen, get it into the blood stream, and down to the muscle where it's used to make energy. This is referred to as your VO2Max. For some sample interval workouts [click here].

Endurance Runs (or long runs) are also beneficial to 5K runners. Usually when you think of a long run, half-marathon or marathon-runners come to mind. Long runs can also benefit shorter-distance runners due to the muscle endurance-building benefits of the long run. "Long Run" is a relative term. Someone training for a 5K doesn't need a run as long as someone training for a marathon. Where a marathon runner may build up to a 20+ mile long run, a 6-, 7-, or 8-miler will suffice as a long run for a 5K runner. These runs are to be run at an easy converational pace, usually about a minute to 1.5 minutes slower than race pace. Think endurance-building, not speed for these runs.

One more workout that I like to throw into the mix is what I call a 1-Mile Pacing Workout. This strategy is great for 5K runners as well as young cross country runners who need help with consistent pacing. This workout is similar in structure to an interval workout, but it doesn't have to be run on a track. It also is similar to a fartlek which is when a runner adds bursts of speed (a fartlek) into a regular run. Unlike these runs though, a 1-mile pacing workout will help a 5K runner do three things:

1. Learn the feel of his/her race pace.
2. Have more evenly paced splits.
3. Experience running consecutive race-pace miles.

Often, because a 5K race is so short, runners will bolt out at the start with an amazing (but unrealistic) pace that they're unable to maintain for the course of the race. Or, they'll start out too slow, only to need a miracle to get that last mile up to the pace they need to achieve the desired finish time.

The 1-mile pacing workout will help a runner achieve a more evenly-paced run which will often result in having a little left in reserve at the end, so if desired, he/she can pull out the stops during that last tenth of a mile for a fast finish.

First the runner needs to determine the desired race time goal. For an example, let's say a runner want' to achieve a 21:00 5K. His 1-mile pacing workout would look like the following.

5-10-minute warm-up jog
1-mile at a 7:00min pace
4:00min recovery run at slow pace
1-mile at a 7:00min pace
4:00min recovery run at slow pace
1-mile at a 7:00min pace
5-10-minute cool-down jog

During the next 1-mile pacing workout, the runner repeats the same workout, but decreases the recover runs to 3-minutes. During the next workout, the recover runs decreased to 2-mintues, then 1-minute, and eventually to 0 mins and the runner will be doing three consecutive 7-minute miles.

Note: If your goal is to run a 21:00 5K, but you're not yet capable of running a 7:00 mile, then your initial set of workouts should be at a pace you can run. So, maybe you begin with 8:00miles and once you can do three 8-minute miles consecutively, then you can go to a series of workouts running 7:30-minute miles and so on until you get down to the 7:00 minute pace.

SHAKE IT UP, BABY! 5 Tips for Increasing Speed

When you're a new runner, each race is so exciting. Because you're new to the game, your learning curve and you body's adaptability curve is huge. So, you see progress with each run. And with each race your finish time decreases. That's an awesome feeling. All that hard work you've put in is really paying off.

Skip to a few years (and miles) down the road and you're not seeing as much progress and your times seem to have stagnated. What's the deal? I hear it and read about it all the time...."I run and run, but I just can't seem to get any faster."

The good news is that you havent' become weaker and no it's not that you're declining as a runner, it's just that your body has now adapted to the stress of your normal weekly routine and because of this acclamation, your body doesn't see the need to adapt any more. So what do you?

You SHAKE IT UP, BABY! What you're body needs is a jolt...a wake-up call. Listed below are 5 Shake-It-Up-Strategies one or more of which you can add to your weekly routine to help get you over that "stagnation wall" and on your way to setting a new PR.

1. Intervals:
One of the best ways to improve your race time is to add a weekly interval workout to the mix. This workout will be short mileage-wise, but it may be your hardest workout intensity-wise for the week. Typically the total mileage in an interval workout is about 3 miles (maybe 4 counting the rest intervals). Find a track (or a flat empty parking lot) where you can easily keep track of 200m, 400m, 600m, 800m, 1000m, etc., intervals. The parking lot at a local park near my house is a half-mile loop so it's great for doing 800s. Typically the longest interval is a 1600m (1 mile). Shorter intervals are usually run at your 5K pace and longer intervals are typically run at your 10K pace. The McMillan Running Calculator is a great tool to help you determine the speed at which you should do various interval distances. Just plug in the race distance you're training for and hit "calculate" and it will break down the training times for a zillion different distances. For me the times are a little fast, so remember that you may need to work up to the times they recommend. Any variety of interval distances in a workout will do. I like to mix it up.

Yasso 800s—Created by Bart Yasso, the race services manger at Runner's World—are great for marathon training and are directly tied to your marathon goal time. If you want to do a 3:30 marathon, then you run a series of 800m intervals in 3mins:30seconds. Your recovery intervals in between each 800 is the same amount of time as you did your 800. So basically a 3hr:30min marathoner wannabe will run an 800 interval in 3mins:30secs then do a recovery jog at a much slower pace for 3mins:30secs and then repeat with the another 3:30 800. Note: These are tough!

I like variety, so when I'm training, each week I'll mix it up a little. Here's a typical interval workout schedule I like to use. It covers six weeks, and then I just start over with Workout #1 again. Give it a Try! Workout #6 is a killer!

Workout #1—5x1000m @5K race pace with 2-minute recovery (walk or jog) in between
Workout #2—6x800m @10K race pace with 90-second recovery (walk or jog) in between Workout #3—Three sets: 1x1200m @ 10K race pace with 1-minute recovery, 1x400m @5K race pace with a 3-minute recovery (walk or jog) in between each set
Workout#4—4x1600m @10K race pace with 3-minute recovery (walk or jog) in between
Workout#5—8x800m @10K race pace with 90-second recovery (walk or jog) in between
Workout#6—400m @ 5K race pace (30sec recovery); 800 @ 10K race pace (90-sec recovery); 1200m @10K race pace (2-min recovery); 1600m @10K race pace (3-min recovery); 1200m @10K race pace (2-min recovery); 800 @ 10K race pace (90-sec recovery); 400m @ 5K race pace

2. Hill Work
Uphill running helps you learn to recruit fast-twitch muscle fibers which will help you run at maximum intensity. Learning to recruit these fast-twitch muscles will help you during an endurance run when you need to ramp it up or when you need to pull yourself out of fatigue.
-
Downhill running is also great. Thanks to gravity, you naturally run faster going downhill. This is a great way to see what it's like to run at a faster pace and with a faster turn-over. This is hard to experience on flat ground. Just like adding extra miles, your body has to adapt to running faster. Ever blow it out at the end of a race and you feel like you have absolutely no control of your limbs? They're just flying everywhere? That's because you're asking your body to do something it really doesn't know how to do yet. Be careful, though. The decline doesn't have to be steep. A 5-7% decline is more than enough. You don't want to lose your balance and get an injury from rolling down the hill.

3. Faster Turnover
More and more research is showing that a shorter stride with a faster turnover rate is a more efficient way to run. It's less taxing on the body and helps to prevent heel striking which can cause a breaking effect that can actually slow you down (as well as not being very good on your feet, knees or back). So, don't worry so much about your stride length. Instead focus on improving your stride rate. Most elite runners have about 180 strides per minute. Check out your stride rate by going for a run and counting each stride for a minute. (Note: an easy way to do this is to count each time your right foot hits the ground for a minute and then multiple that number by 2.) Don't be shocked if you're nowhere near 180. But, just by focusing on cadence you'll be pleasantly surprised when you recheck your stride rate. I bet you'll see an increase. Don't be surprised if your legs are a little sore after working on a shorter stride. You'll actually kick in some muscles that may not have been recruited as much in your longer stride. Keep at it though. That soreness should subside after a few runs.

4. Tempo Runs
A tempo run is simply a run (usually 4-8 miles) that's run at a faster pace (typically a little slower than your 10K pace). Warm up for a mile, then do 2-6 miles at tempo pace and then do a cool-down mile. For example for a 4-mile run, run 1 easy warm-up mile, 2 miles at tempo pace, and 1 easy cool-down mile. Be sure to start with a shorter distance for your first tempo runs before working your way up to the longer tempo-run distances. Tempo runs are the bridge between those weekly slow runs and your fast-paced race. They help prepare your body physically for the demands of running at race pace as well as help prepare you mentally for the demands of running at a faster pace.

5. Drop 5-10 lbs.
Easier said than done, but dropping 5-10lbs will help increase your speed. Some research shows that it can decrease your race time by 1-2 minutes.

Runners Round Table Podcast: Stretching and Other Running Topics!

Check out the Runners Round Table podcast below recorded live on 11/18/09 with runners from the US, England, and Canada. RunnerDude was greatly honored to be invited to co-host the podcast along with Toni, host of her blog, drusy.blogspot.com. and Melisa, host of her blog, irishblue.blogspot.com. We talked with the featured guest, Yuri Elkaim - athlete, author and Fitness/Wellness Expert. A former professional Soccer player, Yuri is the founder and owner of Total Wellness Consulting, hosts a blog Fitter U Fitness, and has written Eating for Energy (www.eatingforEnergy.ca) and Nutrition for Runners (www.myTreadmillTrainer.com) as well as articles in Beyond Fitness magazine, Impact magazine, and Fitness Business Canada magazine.

The pod cast is about 50 minutes and well worth the listen. Yuri and the group discussed the difference between dynamic stretching and static stretching and the importance of stretching for injury prevention. Yuri discussed his approach of incorporating more raw fruits and vegetables into your diet and consuming foods in their "unprocessed" state and how doing this improves your training and recovery time. The group also briefly discussed interval training and how it can benefit all runners' training.

The Benefits of Interval Training

My Marine Corps Marathon training is kicking in soon and the FIRST training plan that I'll be using along with my running buddies has us scheduled for an interval workout each week. I know interval workouts help increase your overall speed, but I wondered what other benefits you gain from doing a weekly interval workout. Here's what I found.

You'll burn more calories. Yep, that's right. Recent studies (i.e., American College of Sports Medicine), show that short intense runs such as intervals or fartleks can be very beneficial to weight loss. The Mayo Clinic also says that the more vigorously you exercise, the more calories you'll burn — even if you increase intensity for just a few minutes at a time.

You'll increase your endurance. As your cardiovascular fitness improves you'll improve your aerobic capacity which means you'll be able to exercise longer and more intensely.

You'll be able to better adapt to the demands of an endurance race. Interval training works both the aerobic and the anaerobic system. During the intense running of your interval workout, your muscles use stored glycogen for energy. This is the Anaerobic system at work. Because the anaerobic system doesn't use oxygen, it gives off a by-product called lactic acid which results in that burning sensation you feel in your muscles. When you jog for recovery in between intervals, your heart and lungs work together to add oxygen back into the muscles, breaking down the lactic acid. This is the aerobic system at work. Doing intervals on a weekly basis helps teach your body to build up a higher tolerance to lactic acid buildup. It also strengthens your heart. In a nut shell, this means improved performance and improved endurance. So speed work actually helps endurance runners become more efficient runners.

You won't need any fancy equipment. All you need is a track, but actually you don't even need that if you can find a flat area and measure your repeat distances. Getting to a track can sometimes be difficult for me, but I discovered that the parking lot at one of our local parks is a half-mile loop which is basically 800meters. Perfect for interval training.

You'll make your training week more interesting. Not only will you have a different experience to look forward to, you'll eventually begin to see how your other "regular" workouts are beginning to benefit from your interval training.

You'll feel amazing after an interval workout. During the workout you may be cursing, but afterward, the sense of accomplishment is very rewarding.

Consistent interval training can help to lower your resting heart rate. The more blood pumped per beat the less your heart needs to beat each minute. The more blood pumped per beat the LESS your heart needs to beat each minute. That's a good thing!
