Even Split

The second half as fast as the first

Plan structured workouts on the web, run them on your Apple Watch, and see what they did to your fitness. Free — for runners who coach themselves.

Planning, your calendar and your training-load metrics are free forever.

If Even Split ever charges for anything, it will be AI-coach depth and device integrations — nothing else, and never retroactively.

The Even Split dashboard: four figures for the week — 3 sessions, 14.2 km, 2h 41m and 175 TSS of load — above a strip listing that week's sessions day by day and closing on a total of 14.2 km, 2h 41m and 175 plus ~11 TSS still planned; then the Fitness, Fatigue and Form chart, its range control set to 90d — Fitness 13 rising +2.1 per week, Fatigue 28, Form −10, with a dashed projection continuing past today to the last planned session — and the training calendar, where completed runs carry a tick and their load (51, ~66 and 58 TSS) and planned sessions stay dashed with estimated load (~11 TSS). Light theme.

What works today, what I'm building, and what I've decided not to build. Nothing moves to Live now until it works end to end.
