What is the workout? Strides aren't a workout per se , more like an addendum to your regular running schedule. Typically you'll finish up an easy or normal run with 4-10 strides of 80-120 meters. So what's a stride? It's a short sprint at sub-maximal effort (somewhere between 80 and 120 meters; doesn't have to be exact, just eyeball it) followed by full recovery between reps (about a minute or so walking around; again, doesn't have to be exact, just feel fresh before your next one). This is all done by feel...run at a relaxed-fast, near effortless speed; no straining, no flailing, no racing. Don't worry about splits, don't worry about pace; just run smooth so you can feel fast and focus on solid form. Think of these like the running version of free-throw practice. (Edit: if you really wanted to, you could make strides a stand-alone workout: warm up, then run 10-30-ish strides with full recovery , then cool down.) Why should you do it? You should do...
