An AI running tool that builds kilometre-by-kilometre race strategies from a course, goal time, elevation profile, and race-day weather.

Landing page captured for the 2026-08-31 issue.

Field notes

The tool combines a selected race or uploaded GPX route with a target time, recent result, elevation profile, and forecast for the expected start time. Its examples show the intended granularity: a flat kilometre at 4:13/km can become 4:27/km on a climb, while headwind is calculated against each segment’s route heading. Outputs include printable and lock-screen formats, a Garmin course export, and guides for COROS and Apple Watch.
