I The argument

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.

Everything in one place.

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

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.

Your data belongs to you.

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

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.

II The collection

What you get.

I

Tracking

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

II

Analyze

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

III

Connect

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

IV

Challenge

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

V

AI Coach

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

VI

Planning

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

III The origin

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.
