Running Nowhere Fast? Try These Tips for Increasing your Pace

Seems like if you want to get faster, you'd just pick up your pace. Sounds like a simple solution, but like many things in life, what seems simple often is not. Many runners have come to the studio saying, "I just can't seem to get past a certain pace. I try to pick it up, but nothing happens or worse, I begin to slow down."

To increase pace two things need to happen. 1. Increase VO2Max  2. Build endurance. VO2Max is your body's ability to utilize oxygen at the muscle layer at maximum exertion. Your muscles have a network of tiny blood vessels (capillaries) that carry oxygenated blood to the muscle. If your runs are pretty even and you don't vary your pace too much, your network will be more like sprawling country roads--few and far between. To increase your pace, you need a metropolitan network of highways. Good news is that you can build those new highways of capillaries. How? By doing various types of speed work on a regular basis.

Adding one speed workout to your regular weekly running routine will start the construction process. When you consistently add those workouts, your brain will realize that you're not going to stop this. It wants your body to work as efficiently as possible, so your body will actually begin to increase the network of capillaries in your leg muscles to help meet the new energy production demands. The more capillaries you have in your muscles, the more oxygenated blood will reach the muscle. The more oxygenated blood in the muscle, the more potential for energy production.

As the network of capillaries grows your body will also increase mitochondria (the energy-making power houses of the muscles.) Mitochondria use the oxygen to create energy. So, now with the increased network of capillaries and increased number of energy-making power-houses, your body will be able to meet the energy demands to get you going faster.

It takes commitment, consistency, and hard work to create that metropolitan highway network. It may be tough at first. Expect soreness and fatigue. Anytime you increase the intensity level of your workouts, your body will react. This is called the gain threshold. Your fitness level may even dip for a few weeks. That's when most people give up. They're not seeing results fast enough and they get discouraged. "I feel worse that before I started. Why am I doing this?" But, like I tell my runners, "Trust. Believe. Conquer!" It varies from person to person, but anywhere from 4-6 weeks you'll notice that you're stronger and faster than when you started.

The gain threshold is the reason why it's not a good idea to add new intensity just before a big race. You're body will not have time to acclimate and it may hurt your performance.

The Workouts:
I like having my runners do two types of speed workouts. One type is shorter, but more intense. Intervals are a great example of this. Don't worry, for many interval-based workouts, you don't need a track. The second type is a fast run but incorporated into a longer distance. Progression runs and Tempo runs are great examples.

Below is plan to help you ease into adding speed work into your running routine to help you run faster and longer. This is just a suggested plan. You'll need to increase or decrease running days based on your experience as well as your schedule. If you're having to rearrange the runs to better suit your schedule, remember to never pair two hard runs back-to-back. Always follow the Easy/Hard/Easy rule. The workouts listed on the schedules are described at the bottom of this post.

Easy Run with 3 Fartleks:  "Fartlek" is a Swedish term for "speed play." Take one of your regular weekly 3-6 mile runs and add in 3 bursts of speed. The first week keep the burst of speed at 2-minutes for each fartlek. Remember to space the fartleks out. Do one fartlek in the first third of your run, the one in the second third and then one in the last third. Between fartleks, be sure to slow the pace back down to your original easy pace. During your second week, try increasing the fartlek duration to 3-4 minutes.

Interval Workouts:
Mona Fartleks: Mona Fartleks are a great interval workout that you can do anywhere. You don't need a track. You'll need a stopwatch or sports watch with a timer. For the workout do a 1-mile warm-up run, then run...
15 seconds fast/15 seconds slow/15 seconds fast/15 seconds slow
30 seconds fast/30 seconds slow/30 seconds fast/30 seconds slow
60 seconds fast/60 seconds slow/60 seconds fast/60 seconds slow
90 seconds fast/90 seconds slow/90 seconds fast/90 seconds slow
That's 13 minutes of fast/slow intervals. Take a 2-3 minute walk or easy jog break, then repeat for a second 13-minutes of fast/slow intervals. Follow-up the workout with an easy 1-mile cooldown.
Timed Based Pyramids: This workout is similar to the Mona Fartlek, but for this workout you'll increase the time increments and then come back down. Before the workout, do an easy 1-mile warm-up run. Then for the Timed Pyramid workout run...
30 seconds at high intensity/1-min at low intensity
45 seconds at high intensity/1-min at low intensity
60 seconds at high intensity/1-min at low intensity
90 seconds at high intensity/1-min at low intensity
60 seconds at high intensity/1-min at low intensity
45 seconds at high intensity/1-min at low intensity
30 seconds at high intensity/1-min at low intensity
Walk or easy jog  for 2-3 mins and then repeat.
Follow-up the workout with an easy 1-mile cooldown run.
90s/60s: Do a 1-mile warm-up run. Then run hard 90 seconds /Run Easy 60 seconds. Repeat 5 times. Then walk or do and easy jog 2 mins then repeat the 90/60 workout again. Follow-up the workout with an easy 1-mile cooldown run.
Progression and Tempo Workouts:
Progression Run: "Thirds," involves doing the first third of the run very slow and working into an easy pace, the next third  at your regular "in-your-groove" pace, and the final third increases until you're  finish the last 3rd around your 10K race pace—roughly 80 to 90 percent of maximum heart rate. Increases in pace are not "step-wise" but gradual. Basically start really slow. Slower than you normally run and gradually increase pace until the end of the last 3rd, you're coming in pretty fast.
Tempo Run: Begin with a 1-mile warm-up run and end with a 1-mile cool-down. The miles in between are run at a pace about 30 secs slower than your 10K race pace.
Tempo Interval Run: Begin with a 1-mile warm-up run and end with a 1-mile cool-down. For the miles in between, alternate running 5 mins at a pace that's about 30-sec slower than your 5K race pace and 5-mins at an easy pace. Cycle through as many of these fast/slow intervals until you reach your cool-down mile.

Keep in mind that during the fast portion of the runs, you should be reaching a pace that's non-converstional. In other words, it should be hard to talk in more than one- or two-word sentences. Be careful not to go so fast that you can't catch your breath or that you can't maintain the interval pace. Initially start conservative with your increased paces and then as you begin to acclimate, start to up the pace. 

Following this plan for 5 weeks will help you see results in achieving a faster pace and pretty much get you through that gain threshold. Keep at it and you'll continue to see even more progress. This is a great primer for a 5K or 10K race. Start about 12 weeks in advance of the race. If you're not planning on racing any time soon, after the first 5 or six weeks, you can keep just one speed workout or tempo/progression run in your weekly routine until you're ready to kick it up a notch for a race.

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.
