When life happens work, sleep, travel, illness Rocket adjusts. Miss a session and your week reshapes around what's left. Get stronger and the load increases. Race week? Rocket tapers you automatically. It's the same logic a personal coach uses, built into your phone.

Your training should be too. DISCIPLINES - Triathlon - swim, bike, run (Sprint โ IRONMAN) - Running - every distance, every goal (5km โ Ultramarathon) - HYROX - Singles and Doubles (Open โ Pro) - Strength - built for athletes who race - Cycling - power on the bike - Swimming - technique first - Mobility - move better, train longer - Breathwork - nervous system reset HOW IT WORKS 1.

You run and you lift. You race triathlon and HYROX. You're chasing a marathon PB and a 5K. Until now, training across disciplines meant hiring a coach or stitching together three different apps. Rocket replaces all of it. One engine for every race. Now accepting founding members. Free during beta.
