Chapter I

Your training stack, finally under one roof.

Most athletes pay for a tracker, a calendar, a coach, a social feed, a strength app — four tabs, 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.

— 01

Everything in one place.

Live GPS recorder, Garmin sync, plan builder, AI coach, strength log, route builder, friend feed, challenges, race predictor.

— 02

Less than any single tool.

Premium is $8/month (or $80/year). Below the monthly price of almost any single piece of the stack you’re running today.

— 03

Your data belongs to you.

European servers. Bulk export to CSV/JSON. No upsells that lock historical data behind a paywall.

— 04

Plans that read your training.

Periodised by VDOT / FTP / CSS, recovery trend, A-race taper. Sport-specific engines, not a running plan with a different label.

Chapter II

The catalogue.

— 01

Tracking

Live GPS recorder, unlimited Garmin sync. Follow a planned workout with audio cues, or just press start.

— 02

Analyze

VDOT, lactate threshold, HR zones, pace trends, race predictions. Every session auto-analysed with rules-based feedback.

— 03

Connect

Follow other athletes, see their runs, comment on routes, drop a kudos. Unlimited feed on the free tier.

— 04

Challenge

Weekly distance or elevation challenges, group streaks, leaderboards. Create your own for Premium; join any at no cost.

— 05

AI Coach

Ask training questions in plain English, get narrative answers tied to your actual data. Premium unlocks deep narrative on every run.

— 06

Planning

Pick a sport. Pick a race. The plan builder generates a periodised schedule and pushes it to your Garmin calendar.

Chapter III

Built for athletes.

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.
