A free web app that turns IGC tracklogs from paragliding competitions into interactive 3D replays: every pilot, the task with turnpoint cylinders, and a live leaderboard on photorealistic terrain.

How do I watch a replay?

Open any event from the archive and press play. Follow individual pilots, chase the leader, speed time up, and scrub to any moment — in the browser, nothing to install.

What data does it use?

Standard IGC GPS tracklogs recorded by flight instruments and apps such as XCTrack. The task is imported from competition scoring files; rankings are computed along the timeline.
