The problem
You wrote your goal splits on your hand.
Every Hyrox athlete does it. There's no tool that tells you — in real time — whether you're actually on track.
Every app is just a stopwatch
You get splits after the race. You need them during it. Knowing you ran 4:22 on Run 3 is useless — knowing you need to run 3:51 on Run 4 to stay on target is everything.
Going out too hard destroys your race
Run 1 adrenaline is real. You push hard, blow your HR, and pay for it on Wall Balls. By then it's too late. You need live feedback, not a post-mortem.
No app shows you the cumulative delta
You're 17 seconds behind pace right now. If you push the next run, you can claw back 12 of those seconds. No existing app tells you this. We built the one that does.
How it works
SET.
RACE.
KNOW.
Three steps. One crown press per run. Everything else is automatic. The watch does the maths so you can focus on the race.
STEP 01
SET YOUR PLAN
Set up on iPhone before race day — enter your goal time, tell us your strongest and weakest stations, and we generate personalised splits for all 16 segments. Sync to watch in one tap. No iPhone needed on race day.
STEP 02
RACE ON YOUR WRIST
Crown press at the end of each run. Station clock starts automatically. The briefing card shows your split result, cumulative delta, and next station specs — while you're already moving.
STEP 03
KNOW YOUR DELTA
Every screen shows two numbers: segment countdown to your target, and cumulative ahead/behind for the whole race. One glance. No maths. No guessing.

During a run
Mid-run the watch shows elapsed time and a live countdown to your target. No GPS pace — Hyrox runs are indoor and GPS is unreliable. The countdown is the pacing signal. Green = you're within target. Red = you're over.
Segment elapsed time — large, always visible
Countdown to target — colour-coded green/red
Cumulative delta in the stats row
Crown press ends run and starts station clock simultaneously
Division-aware specs
The app knows
every station.
Correct weights and distances for every division, shown on your wrist before each station. You never have to remember 102kg mid-sled.

Why we built this
"I raced Hyrox with my target splits written on my hand. There has to be a better way."
Desmond de Moussac · Founder, RoxPacer
Hyrox athlete and software developer based in Singapore. Built RoxPacer to solve the exact problem I kept hitting on race day — and figured I wasn't the only one.
