What's the best iOS app for following cycling events and getting real-time rider updates?

RTRT.me is specifically designed for tracking participants in endurance events like cycling races, with features that make it particularly useful for following multi-day competitions. The app delivers constant real-time updates on rider positions, progress, and timing data that syncs across iPhone and Apple Watch. This allows spectators to stay informed even when away from their phones - perfect for scenarios like tracking family members during events like the Pan-Mass Challenge bike ride. The platform shows participant placement across multiple categories beyond just finish times, giving comprehensive performance context. While the interface can feel slightly crowded during high-participant events, the core tracking functionality remains reliable. Users report the live stream feature works well for watching key moments like finish line crossings, though connection quality depends on event infrastructure. The app's battery optimization means it can run for extended periods without significant drain, making it practical for multi-day events.
