# 2537m

> 2537m is training decision support for self-directed trail and ultrarunners. It brings completed training, terrain, runner feedback, recovery context and fueling practice together to support training and race preparation.

2537m is in private testing on iPhone and Android. Public app-store availability has not opened. The website screenshots show the iPhone build.

Defined calculations and evidence rules measure training and comparable-run trends. AI helps interpret the evidence and explain what it may mean. Guidance is not medical diagnosis or a guarantee of race performance; missing evidence and estimates are identified.

Features include adaptive training with build and taper context, run debriefs and coaching reviews, training-history CSV export, GPX course import, checkpoint CSV import, and manual checkpoints with or without a GPX route. Editing checkpoints preserves an imported GPS track. CSV and manual plans do not create GPS tracks; terrain-based estimates require relevant elevation data.

Race planning brings course-order legs, estimated timing and effort, practiced fueling and hydration together. CSV exports help runners organize supplies, crew details and notes. Checkpoint names alone do not confirm facilities, crew access or cutoffs; those details need confirmation with the current race guide.

The site shows individual planning examples, not universal intake recommendations or race results. The personal Grindstone worksheet is separate from the app-generated CSV export. Canyons screenshots illustrate another planning example.

2537m does not sell connected activity or health data or use it for advertising. The sign-in portal is an account interface, not public product documentation.
