Running Strides: All You Need to Know

Running strides on a regular basis can do wonders for your running performance. It might be your missing piece en route to a new personal record. 

“Strides have a major impact on your running economy.”

Moreover, strides are easy to implement into your existing running routine without overly taxing your body.

What Are Strides?

Strides go by many names. Striders, stride-outs, accelerations, and pick-ups. 

They are typically 50 – 150 meters long or 10 – 30 seconds in duration, with an intensity ranging from 5K race pace to 400m race pace. If you are training for shorter events such as the 5K and 10K, then running strides is in the faster range, and vice versa for HM and marathon runners. But strides are NEVER all-out sprints! 

Also, strides are rarely a standalone workout (although, in some cases, they can be). Rather, they complement your existing runs. Strides can be tacked onto an otherwise easy run to inject some speed, serve as a warm-up for intense workouts, and should be done the day before a race to ensure bouncy legs on the starting line. 

The Benefits of Running Strides

Strides have only a minor effect on your aerobic capacity (VO2max). But, they significantly impact your velocity at VO2max (vVO2max). What’s the difference between the two? vVO2max takes your running economy into account. That means the pace you can run at your maximal aerobic capacity can improve significantly even if your VO2 max itself is unchanged. 

Here’s a real-life example of my training. In 2016, after completing a 10K training cycle, I set my eyes on a 400m masters competition. I dramatically reduced my easy mileage to running 5 miles twice a week and dedicated 2 track sessions to anaerobic intervals of 50 – 400m. The result: My VO2max reading on the Garmin increased from 66 to 68 over the 12 weeks of 400m race preparation, despite a complete lack of VO2max intervals and a ridiculously low weekly training mileage.

That’s the power of running economy! It’s fair to assume that my aerobic system declined to some degree. That means the increase in running economy made more than up for it. And I won that 400m dash masters competition (53.8 sec), in case you were curious. Not bad for a distance runner. This ability has helped me outkick competitors and finish photogenically in longer events on pretty much every occasion—unless they killed me aerobically well before the finish line. 

If that anecdote didn’t convince you that running strides is beneficial to your performance, then maybe science will. The effects of strides enhance your musculoskeletal, biomechanical, and neuromuscular systems. Strides improve stride length and cadence via increased force production, more range of motion, and a shorter ground contact time. 

But most importantly, including strides into your existing running routine preserves your speed as you age. 

When Should You Be Running Strides?

There are 3 occasions when running strides is beneficial: 

#1 After an easy run once or twice a week. Since an easy run almost exclusively recruits slow-twitch muscle fibers, a few strides will help you loosen up by engaging your fast-twitch muscle fibers. Not to mention all the sexy benefits I just mentioned with little strain on your system. Start with 1 or 2 strides and add one every week until you arrive at 4 – 8 strides, depending on your level. 

#2 As part of a warm-up for fast workouts, strides are a great neuromuscular primer following 10 minutes of easy running, dynamic stretches, and drills. Two to four accelerations are plenty to rev your system. You can also end a workout with strides, making it a combo stimulus. But don’t overdo it, as more is not necessarily better. 

#3 Pre-race day shakeout. All my training plans include 20 – 25 minutes of easy running with a few strides the day before the race. That way, you won’t feel flat on race day. Of course, you should also do 2 or 3 strideouts on race day to ensure bouncy legs. Before 5K and 10K races do a few pickups at 800 – 1500m race pace and for longer distances 3K to 5K pace will do.

Where to Run Strides

Let me state the obvious first: Run strides where you don’t endanger yourself or others, and avoid undulating terrain. 

I always recommend that my athletes start with uphill strides, or hill repetitions, as I like to call them. The two benefits of hills are more muscle recruitment and reduced landing impact forces. They are great for building running-specific strength in a safe way. 

Once you have established a foundation of strength, you can take the strides to flat terrain. Whether you perform strides on asphalt or the track is up to your convenience. But if you have a track nearby or do your main set there anyway, it’s a better choice simply because the track’s surface is more forgiving. 

If you want to work on a faster leg turnover, you can also occasionally do strides on a slight downhill segment with a 2 – 3 percent grade. Use this method in moderation, as this puts additional stress on your knees. Alternatively, you can use the treadmill for the same purpose: the pace at the same effort is faster, largely due to a lack of wind resistance. 

How to Run Strides

As I mentioned before, strides are typically 50 – 150m long or about 10 – 30 seconds in duration. The fastest strides should be your 400m race pace, which roughly equals 90 percent of your maximum speed. The idea is not to turn strides into an all-out sprint. You will likely tense up and unnecessarily increase your risk of injury. 

Also, remember that even though strides are fast, they shouldn’t be hard. They are intentionally short so that there is not much lactate buildup. For that reason, the rest intervals are typically walk-back recoveries. The purpose of strides is to enhance your running economy and not your VO2 max or your lactate threshold

Most importantly, focus on your running technique. Quick light steps, a slightly exaggerated form, all the while keeping a relaxed face. Pay attention to your knee lift and bring your heels up to your glutes. The arms dictate the pace. There is no need to observe our running watch (and it would be difficult if you tried at that pace). 

Use a flying start, accelerate gradually, hold the peak for a few seconds, and then decelerate until you come to a walk. Leave the starting blocks to whom they belong – sprinters. As a distance runner, you don’t need to work on acceleration at the maximal effort. 

If you happen to run strides on a 400m track, you can use the 100m straightaways to accelerate and walk the turns. You could bring your racing flats (or even spikes). But not all strides have to be fast. Doing a few pickups in the 5K to 3K race pace range is often enough to keep your legs bouncy.
