Strides
Strides are short, controlled accelerations — about 15 to 20 seconds each — that you run fast but relaxed, with full recovery between. They sharpen your mechanics and leg speed for almost no fatigue cost, which is why they show up at the end of easy runs and as part of the warm-up before a hard session or race.
What it does for you
A stride is a brief pickup where you accelerate smoothly to roughly 90–95% of your top speed — fast and fluid, never an all-out sprint — hold that relaxed fast running for a few seconds, then ease off. You recover completely before the next one, so you finish the set feeling springy rather than drained.
Strides keep your legs fast during the high-volume, mostly-easy weeks that make up the bulk of training. They teach your body to run quickly and efficiently, so that when you do race or hit a workout, faster paces feel smoother and more familiar. Done before a hard session, a few strides also wake up the legs so the first repetition does not feel like a shock.
Why it works
Running easy all the time grooves one gear. Strides add a second one without the cost of a real speed workout. Because each rep is short and followed by full recovery, you recruit and train your fast-twitch muscle fibers and rehearse efficient, coordinated mechanics at speed — but you never run long enough to fatigue the muscles or accumulate the damage that makes hard workouts tiring.
Over weeks, that repeated practice of smooth, fast, relaxed running improves your running economy: you use a little less energy to hold any given pace. It is one of the highest-return, lowest-risk additions to an easy run — a small dose of speed that pays off without denting your recovery.
How to do it
Run them on flat ground (or a very slight downhill) with good footing, after an easy run or as part of a warm-up. Build speed gradually over the first few seconds, hold relaxed fast running through the middle, then glide to a stop — never jam on the brakes. Stay loose: soft jaw, low shoulders, relaxed hands, quick light feet. The goal is to practice running fast, not to test how fast you can go.
- Length: about 15–20 seconds each (roughly 80–100 meters). Effort is fast but controlled — you should never feel like you are sprinting or straining.
- Recovery: walk or easy-jog 1–2 minutes between each, fully recovered before the next. The recovery is what keeps strides fresh rather than fatiguing.
- Number: 4–6 to start, up to about 8 as they become routine. Stop the set if your form gets sloppy or anything feels tweaky.
Safety
Strides are low-risk, but they are the fastest running in most easy weeks, so ease in: start with a handful, keep the effort controlled rather than maximal, and run them on smooth, flat ground. Skip them if you are dealing with an ache or twinge that sharpens when you pick up the pace.
Common questions
How long should a stride be?
About 15 to 20 seconds each — roughly 80 to 100 meters. Run them fast but relaxed, never an all-out sprint or a strain.
How many strides should I do?
Start with 4 to 6 and build toward about 8 as they become routine. Stop the set if your form gets sloppy or anything starts to feel tweaky.
How fast should I run strides?
Around 90 to 95 percent of your top speed — fast and fluid, with full recovery between each one so you finish the set springy rather than drained.
