ROXDUO

Pre-launch — training app for HYROX doubles

Built for
Doubles.

Most training apps treat HYROX like a solo sport with a partner bolted on. RoxDuo starts from the doubles format: one AI plan from today to race day, station PBs for both of you, and a Team Sheet that decides who takes what before the gun goes off.

Three things, done properly

01 An AI plan that ends on race day Tell RoxDuo your race and your current level, and it builds every session between now and the start line — running, stations, and hybrid days — then tapers you into race week. Pick your event from the 2026/27 race calendar and the plan counts down to it. 02 Complete today, unlock tomorrow Sessions unlock in a chain: finish today's work and tomorrow's session opens. No scrolling four weeks ahead, no skipping the sled work you hate. It is the same discipline a good coach enforces — one day at a time, in order. 03 Team Sheet doubles strategy Doubles races are won in the split: who takes the first sled push, who owns the wall balls when you are both smoked, where you swap. The Team Sheet turns your station PBs into a who-takes-what plan and a projected finish time — before race day, not mid-race.

Built by an athlete

RoxDuo is built by Filippo Terzi, an athlete training for HYROX Rome (24–27 September 2026) on the same plan the app generates. Every feature exists because it was needed in training — the unlock chain, the station PBs, the Team Sheet. Nothing in the app is theoretical.

FAQ

What is RoxDuo?

RoxDuo is an iPhone training app built specifically for HYROX doubles teams. It generates an AI training plan that runs from today to your race day, tracks your PBs on every station, and plans your race-day station splits with the Team Sheet.

Does RoxDuo work for solo HYROX athletes too?

Yes. The AI plan, station PB tracking, and race time tools all work for singles athletes. The Team Sheet and split strategy features are what make it the best fit for doubles pairs — that is the category the app was designed around.

How much does RoxDuo cost?

RoxDuo is a subscription: €6.99 per month after a 3-day free trial. You see the full plan and every feature during the trial, and you can cancel any time from your App Store settings.

When and where can I download RoxDuo?

RoxDuo is launching soon on iPhone via the App Store. It is iOS-only at launch.
