FAQ
How accurate is the prediction?
It's an estimate, not a guarantee. It's based on what you tell us (e.g. 5 km time, weekly running, station check) and typical time distributions in the race. That's why you always get a range, e.g. ± 4 minutes. The more precise your inputs, the tighter the range – and every retest makes it sharper. Form on the day, the course and the transitions can all affect your result.
I've never done a hybrid fitness race. Is the app still for me?
Yes – especially then. Splitwerk is built for your first or next race. You'll see which finish time is realistic, learn the 8 stations with technique tips and train with a plan that builds up gradually.
My gym has no sled. Does the plan still work?
Yes. In the quiz you tell us whether you train in a gym with sleds and ergs, a regular gym, or at home and outdoors. The plan swaps missing equipment for suitable alternatives.
Can I use the app for doubles?
Yes. Choose “Doubles” in the quiz. The doubles planner splits the stations based on your strengths and shows your combined target time – with a shareable card for your partner.
How does the free trial work – and how do I cancel?
The annual plan comes with a 7-day free trial. We'll send you a reminder before it ends (if you allow notifications). If you don't cancel at least 24 hours before the trial ends, the annual plan starts at €79.99. You can cancel anytime on your iPhone under Settings → [your name] → Subscriptions → Splitwerk.
