Add up your race. See your finish time.
Enter your eight runs, eight stations and your roxzone to get your exact projected HYROX finish time and a live breakdown of where every minute goes. Pure maths on your own splits: no made-up benchmarks, no guesses.
Your splits
The roxzone is the walk in and out of every station: 16 transitions that don’t show on a station clock but quietly add minutes to your finish.

Where the time goes
Every run, station and the roxzone, in race order. The tallest bars are where your race is won or lost.
This is the maths. The why (which split is actually costing you, and what to train next) comes from your real race.
Start trainingThis tool only adds up the numbers you enter. It never invents a split or compares you to a fabricated benchmark. Every value above is yours.
A HYROX time is three numbers added together.
No single split decides your race. Your finish is the sum of the runs, the stations and the roxzone. The calculator above lets you change any one of them and watch the total move.
8 × 1 km runs
Eight identical kilometres, run under accumulating fatigue. For most athletes the runs are the single biggest block of the race, and the first thing to fade.
8 functional stations
SkiErg, sled push, sled pull, burpee broad jumps, rowing, farmers carry, sandbag lunges and wall balls, in that fixed order, every race.
The roxzone
Sixteen transitions in and out of the station floor. The clock never stops, and it never shows on a station split. So it is the time almost everyone forgets to count.
Runs + Stations + Roxzone = Finish. That’s the whole equation. The hard part isn’t the arithmetic. It’s knowing which of those segments is quietly costing you the most, and what to actually train to fix it.
A finish time tells you what. Not why.
Two athletes can share the exact same total and have completely different races. One bleeds time on fading runs; another on a slow sled or a drifting wall-ball set. The calculator shows you the maths. Finding your limiters, and which to fix first, takes your actual race data.
Turn your total into your next PR
When you import an official result, 8stations.ai ranks every split and station against the real field, targets the biggest leak first, and builds a training plan that works through the rest as your data changes, then sets a probability-weighted finish prediction off your trajectory and adapts it every week. That’s the difference between knowing your time and knowing how to beat it.
