Hyrox splits, sims & pacing

What Roxsplit does

Roxsplit is a race-prep logbook built around the exact shape of a Hyrox: eight 1km runs, eight stations, and the transitions in between. Instead of forcing your prep into a generic workout app that has never heard of a sled lane, Roxsplit gives every part of the race its own place — SkiErg, sled push, sled pull, burpee broad jumps, row, farmers carry, sandbag lunges, wall balls.

The heart of the app is the simulation timer. Run a full or half sim in your gym and tap once at every changeover: each run, each station and each transition gets captured as its own split. Afterwards you see exactly where the time went — including the 'roxzone' transition minutes that quietly wreck most first-timers' finish times. Every station also keeps its own PR, history and technique notes, so over a training block you can watch your sled push drop from 4:10 to 3:20 and know the work is paying off.

Before race day, set a goal finish time and Roxsplit lays out a target split for every run and every station, built on the even-pacing approach that consistently beats going out hot. After the race, log your official splits next to the plan and see precisely where you gained and where you faded — then build the next block around it.

No account, no subscription, no coaching upsell. Roxsplit is 100% offline: everything is stored on your device with SwiftData and never leaves it.

• Lap-style timer for full and half race simulations • Per-station PRs, history and technique notes for all 8 stations • Run, station and transition splits tracked separately • Goal-time pacing plan with target splits for race day • Race log with plan-vs-actual comparison • Fully offline, no account, free

What's inside

• Simulation timer — A lap-style timer pre-loaded with the Hyrox sequence: tap once at each changeover to capture every run, station and transition as a separate split for full or half simulations.
• Station tracker — All eight stations as first-class entities with best times, full history, division-specific weights and free-text technique notes.
• Pacing plan — Enter a goal finish time and division and get target splits for every run and station based on even-pacing distribution, editable per segment, presented as a race-day cheat sheet.
• Race log — Log official races with date, venue and division, enter actual splits next to the plan, and see a segment-by-segment gained/lost comparison including total transition time.

Why we built it

Hyrox prep lives or dies on split data — eight run splits, eight station times, and transition time that counts toward the finish — but existing tools are either subscription coaching apps that prescribe workouts without proper split logging, web-only pace calculators, or a Garmin-watch app; there is no simple offline…

What makes it different

Unlike Ironlog, which logs sets, reps and lifting PRs for general strength training, Roxsplit models the fixed eight-run/eight-station Hyrox race format with split timing, transition tracking and a goal-time pacing plan; unlike Coldplunge, which logs cold and sauna exposure sessions, it is a race-preparation tool with…

Who it's for

Anyone who wants honest tracking without a coach, a subscription, or a streak guilting them at 11pm.
