Free online tools I've built for cycling, climbing, and endurance sports.
Editable weekly training planner. Add people, drop in sessions with auto-picked emoji, assign one or many participants, drag to reorder. Saved locally, printable for the fridge.
Upload a GPX route or try a famous climb (Alpe d'Huez, Ventoux, Stelvio, Kona). Interactive map, per-section pacing, IF, TSS, and an exportable race plan.
Research-based calorie estimator for bouldering sessions. Accounts for grade, wall angle, rest time, and intensity.
Pick a chainring, cassette, and wheel. Convert between cadence and speed, with gear ratio, gear inches, and development.
If you do X watts on the front, what does each rider behind need? Watts saved at every position in a paceline, by leader power, pace, and group size.
Estimate Functional Threshold Power from a single max effort. Add weight for W/kg and a performance-band label. Includes the full Coggan 7-zone training zones.
