Every cyclist knows the feeling: you've done the training, built the fitness, but when race day arrives, the course is a mystery. Where does the gradient kick up? How long is that false flat before the summit? Which corner leads to the final climb?

Cyrace was built to solve exactly this problem. It's a focused iOS app that turns your smart trainer into a race course simulator — no subscriptions, no social features, no gamification. Just the route, the gradients, and you.

How it works

Load a GPX file of your race course and Cyrace sends real-time FTMS simulation commands to your trainer, adjusting resistance to match the gradient at every point along the route. Combined with a virtual gearing system, it feels like riding the actual road.

Built for privacy

In an era where every app wants your data, Cyrace takes the opposite approach. No accounts, no cloud sync, no analytics. The app doesn't even connect to the internet. Your training data stays on your device — period.

What's next

We're just getting started. Cyrace will continue to evolve with features that serve one purpose: helping you arrive at your next race already knowing the course by heart. Stay tuned for updates on route library management, performance metrics, and more.
