# Sprinting > Training periodization and progression-tracking software for sprint and track coaches. Coaches plan periodized training (macro/meso/microcycles), prescribe sets against Training Max reference values with live effort-percent computation, run AI-assisted session planning, and track many athletes from one system. Companion iOS app (Sprinter) measures sprint mechanics on-device. Built for the specifics of speed and power training, not generic gym logging. ## About - [Home](https://www.sprinting.run/): What Sprinting is and who it's for. - [Coach demo](https://www.sprinting.run/demo/coach): Interactive walkthrough of the coach session planner. - [Sprinter demo](https://www.sprinting.run/demo/sprinter): The on-device sprint-measurement iOS companion. ## Guides & articles - [GPP1 to GPP2: what changes between training blocks and why](https://www.sprinting.run/blog/gpp1-to-gpp2-what-changes-between-blocks): Moving from general prep to specific prep, volume falls, intensity and specificity rise, and rest lengthens.
