One engine for every race. Rocket is an adaptive training app for athletes who do more than one thing. Triathlon, HYROX, marathon, running, strength one personalised plan, built around your life. Tell Rocket about your races, your schedule and your goals. In minutes you've got a plan structured around your calendar and adapted to your body. Then it keeps adapting week by week, session by session. WHAT MAKES ROCKET DIFFERENT Most apps give you a plan. Rocket gives you a system that adapts. 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. WHO ROCKET IS FOR Rocket is built for athletes who train across disciplines: - Triathletes balancing swim, bike and run - HYROX athletes mixing strength and endurance - Runners chasing PBs from 5K to ultra - Marathon runners who lift - Anyone juggling more than one race a year The body is one system. 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. Tell Rocket about you. Your races, your schedule, your goals. Takes minutes. 2. Get your plan. A personalised, multi-discipline plan structured around your calendar. 3. Train. Every session ready. Every workout synced to your watch. 4. Adapt. Life changes. Your plan adjusts. Rocket manages your load week by week. 5. Race. Then you do it all over again. FEATURES - Personalised plans built around your races - Adaptive load management across disciplines - Up to 10 races per year on one plan - Strava sync - Apple Watch and Garmin compatible - Built by real coaches, backed by science - Performance Council of physios, sports scientists and elite athletes - Discipline leads for every sport PRICING Personal coaching costs $300โ€“$600 a month. Rocket costs $19.99 USD A full year with Rocket costs less than a single month with a coach. Same intelligence. Fraction of the price. WHY ROCKET EXISTS Most athletes don't fit in one box. 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. SUBSCRIPTION & FREE TRIAL Rocket Premium is available as a monthly or annual auto-renewing subscription with a 7-day free trial. Payment is charged to your Apple ID at confirmation of purchase and renews automatically unless cancelled at least 24 hours before the end of the current period.
