Strides are short running segments—typically 80 to 100 meters—where you accelerate from easy pace to about 95 percent of your maximum effort, allowing you to reset your running form during long runs. Rather than maintaining one monotonous pace for the entire duration, inserting strides toward the end of your long run gives your legs a chance to practice better mechanics when they’re fatigued, which is when form tends to deteriorate most. This simple technique has become a staple for runners preparing for marathons or half-marathons because it trains your body to move efficiently even when your muscles are tired—exactly the condition you’ll face at mile 18 of a race.
The beauty of strides during long runs is that they don’t require a special workout plan or additional time investment. You’re already running; you’re just changing your pace for brief periods. A runner training for a marathon might do four to six strides of 80 to 100 meters each, separated by easy-paced jog recovery. For example, if you’re scheduled for a 16-mile long run, you’d complete 15 miles at an easy conversational pace, then finish the final mile with strides inserted every 200 meters or so, giving you three to four opportunities to practice engaged running when it matters most.

How Do Strides Help Reset Your Running Form on Long Runs?
Strides work because they force your neuromuscular system to activate when fatigue is setting in. During easy-paced running, your form naturally deteriorates—your cadence drops, your stride shortens, your posture rounds forward. By accelerating to a faster pace, even for just 20 to 30 seconds, you’re sending a signal to your nervous system to “wake up” and engage your core, glutes, and stabilizer muscles. This neural activation carries forward into your subsequent easy running, where you’ll notice improved posture and a quicker, lighter stride pattern.
The comparison between running without strides and running with strides is striking in terms of how your body feels. A runner who logs 16 miles at an entirely steady, easy pace may finish with shuffling legs, a collapsed posture, and poor hip extension—all signs that form has degraded significantly. That same runner who includes six strides in the final mile will finish stronger-feeling, with better body alignment, because the strides essentially “reset” the muscular and neural patterns. This reset doesn’t mean you’ll feel fresh at the finish; it means you’ll feel like you still have some control and efficiency, which is the goal.
Why Form Breakdown Happens During Long Runs
Form deterioration during long runs isn’t a character flaw or a sign you’re weak—it’s a physiological inevitability. Your glycogen stores deplete, your central nervous system fatigues, and your muscles accumulate metabolic byproducts. When these things happen, your body takes energy-conserving shortcuts: your stride shortens, your turnover slows, and your posture becomes more compact as a way to reduce the muscular demand. The problem is that if you’ve only practiced running at that degraded form, your body becomes very good at running inefficiently, and that’s the form you’ll carry into the final miles of a race.
The limitation here is important: strides during a long run won’t solve chronic form issues like overpronation, excessive heel striking, or muscle imbalances. If your form is already poor at easy paces, strides won’t fix it during the hard portion either. What strides do is maintain the form you already have and prevent it from getting worse. If you have structural form problems, you’ll need dedicated drills, strength work, or professional gait analysis to address them. Strides are a maintenance tool, not a correction tool.
When to Insert Strides Into Your Long Run
Timing matters when incorporating strides into your long run. Most coaches recommend saving strides for the final quarter or final third of your run, when fatigue is most pronounced and your form is most likely to break down. This is the point where the practice effect is greatest—you’re training your body to hold decent form when it’s hard, not when it’s easy. A 20-mile long run might include strides only during miles 17 through 20, for instance. Some runners make the mistake of inserting strides too early in the run.
Doing strides at mile 5 when you’re feeling fresh and strong doesn’t provide the same training stimulus as doing them when you’re genuinely fatigued. The goal is specificity: you want to practice maintaining form under the exact conditions you’ll experience in a race. Another example is a runner who spaces strides too close together. If you do a stride, recover for 30 seconds, and immediately do another stride, you’re not giving your easy-pace running the chance to benefit from the reset. A better approach is 200 to 400 meters of easy recovery between strides, giving you time to consolidate the neural improvements before the next acceleration.
How to Execute Strides Correctly During a Long Run
The execution of a stride is straightforward but easy to get wrong. Start with 20 to 30 seconds of gradual acceleration from your easy pace, building up to about 85 to 95 percent of your maximum effort. You’re not sprinting—you’re not going all-out for a personal best. You’re accelerating to a pace that feels controlled and sustainable for that short 80- to 100-meter window. Once you reach that faster pace, hold it for a few more seconds, then gradually decelerate back to your easy pace over the final 10 to 15 seconds.
The tradeoff in stride execution is between effort level and recovery. If your strides are too easy, they won’t engage the neuromuscular activation you’re looking for. If they’re too hard, they create unnecessary fatigue and risk turning your long run into a workout rather than a steady aerobic run. Most runners find the sweet spot is around 85 to 90 percent effort—fast enough to feel noticeably quicker than your easy pace, but controlled enough that you’re not gasping for breath or losing your composure. A practical comparison: your stride pace should feel like the pace you’d use during a road race, not like a sprint finish.
Common Mistakes and Form Faults to Avoid
One of the biggest mistakes runners make with strides is allowing poor form to sneak in during the acceleration. Because strides are faster, there’s a temptation to overstride—reaching your leg out in front of your body rather than landing it underneath. During a long run when you’re fatigued, this is even more likely. The warning here is important: if you practice overstriding during your strides, you’ll ingrain that pattern, and it will show up in your race.
Focus on maintaining a quick, controlled cadence during the stride, landing your feet under your hips rather than reaching out. Another limitation is that some runners use strides as an excuse to do too much volume or intensity. A long run should still be a long run—the strides are an accent, not the main event. If you find yourself needing strides to feel “good” during a run, it might be a sign that your easy-run pace is actually not easy enough, or that you’re under-recovered from previous training. Strides should feel like a natural part of the run, not a heroic effort to salvage a difficult day.
Strides Versus Other Form Correction Methods
Strides serve a different purpose than dedicated form drills like high knees, butt kicks, or A-skips. Those drills are typically done as warm-up exercises before a run and target specific movement patterns in isolation. Strides, by contrast, practice form in the context of actual running at faster paces. Both approaches have value—drills are excellent for activation and teaching your muscles what good form feels like, while strides are excellent for practicing that form under fatigue.
Many serious runners use both: drills as part of a warm-up routine, and strides as part of their long runs. Strength training for the hips, glutes, and core also plays a complementary role to strides. Strides train form under fatigue, but if your hip muscles are weak or unbalanced, that weakness will eventually show up no matter how much you practice. Runners who combine consistent strength work with strides during long runs see the best form retention over time.
Building Strides Into Your Training Plan Long-Term
Once you understand the value of strides, the question becomes how to integrate them consistently. For runners training for a marathon or half-marathon, including strides in most long runs—perhaps four to six strides in the final mile or two, done twice a month—creates a cumulative training effect. Your body learns to maintain better form under fatigue, and this carries over into races and even easier training runs.
Looking forward, many elite distance coaches now recommend strides not just during marathon training cycles, but as a permanent part of distance runners’ training. The idea is that maintaining form under fatigue is a skill that takes time to develop and even longer to maintain. Runners who make strides a regular habit, rather than something they do only during race preparation, report better efficiency and fewer form-related injuries over their running careers.
Conclusion
Strides during long runs are a practical, low-cost method to reset your form when fatigue is setting in, and they provide the specific training stimulus of practicing good mechanics under race-like conditions. They’re not a silver bullet for form problems, but they’re a valuable tool for maintaining the form you’ve developed through other training.
The key is executing them correctly, placing them late in your run when fatigue is highest, and treating them as a regular part of your training rather than an occasional addition. If you’re starting to integrate strides into your long runs, begin with three to four strides in the final mile of one long run per week, and pay attention to how your legs feel and how your form responds. Over time, you’ll develop a feel for the right pace and spacing, and strides will become a natural part of your preparation for longer races.
Frequently Asked Questions
How fast should I run during a stride on a long run?
Your stride pace should feel noticeably faster than your easy pace—typically around 85 to 90 percent effort, or roughly the pace you’d maintain during a 10K race. You should feel engaged and working, but not gasping for breath.
How many strides should I do at the end of a long run?
Three to six strides of 80 to 100 meters each is standard. More than six strides can create unnecessary fatigue; fewer than three may not provide enough practice stimulus.
Can I do strides on every long run?
Yes, most runners can include strides on every long run. They’re relatively low-volume and don’t create the same fatigue as a tempo run or interval workout.
What if my legs feel too tired to do strides?
If you feel unable to accelerate at all, your overall training volume or intensity may be too high, or you may not be recovered from the previous day. It’s better to skip strides than to force them when genuinely exhausted.
Do strides replace form drills like high knees or butt kicks?
No, they serve different purposes. Drills warm up your neuromuscular system and teach isolated movement patterns; strides practice form in the context of actual running at faster paces. Both are valuable.
Can I do strides during a marathon race itself?
You could accelerate briefly, but traditional strides are most useful during training. During a race, focus on maintaining the best form you can with the fitness and fatigue you have at that moment.
