Live GPS recorder on the phone plus unlimited Garmin sync. Follow a planned workout with audio cues, or just press start.
One platform for runners and endurance athletes. GPS recorder, Garmin sync, plan builder, AI coach, strength log, social feed — in a single account.
Most athletes pay for a tracker, a calendar, a coach, a social feed, a strength app — four tabs, four logins, four subscriptions, none of them talking to each other. SPLIT replaces the stack with a single account that actually plans your week off your real data.
Live GPS recorder, Garmin sync, plan builder, AI coach, strength log, route builder, friend feed, challenges, race predictor.
Premium is $8/month (or $80/year). Below the monthly price of almost any single piece of the stack you’re running today.
European servers. Bulk export to CSV/JSON. No upsells that lock historical data behind a paywall.
Periodised by VDOT / FTP / CSS, recovery trend, A-race taper. Sport-specific engines, not a running plan with a different label.

Pick a sport. Pick a race. The plan builder generates a periodised schedule and pushes it to Garmin.
SPLIT started as Mark’s personal training dashboard on the road to a sub-80 Copenhagen Half Marathon. It grew into a full platform once the core engine proved it could actually help someone hit a real race goal.
