The Science Behind Our Training Plans
From a fast 1 Mile track block to a 100K ultra marathon, structured periodization keeps you progressing safely. StrideAi applies progressive overload, step-back recovery weeks, and polarized training (the 80/20 rule) alongside Jack Daniels’ VDOT pace formulas to target the exact physiological system required for every run.
Progressive Overload
Weekly volume scales gradually with step-back recovery weeks every 3–4 weeks so tendons and joints adapt without breaking down.
Polarized 80/20 Pacing
Conversational easy runs surround speedwork and weekend long runs so glycogen stores replenish before your next key effort.

“I built StrideAi because I needed a better way to create structured, periodized training plans for my friends, the athletes I coach, and myself. I used the AI-generated 5K plan for my own training block and improved my PR by over 2 minutes. It takes the guesswork out of pacing and progression.”
