What file formats does Race Recon accept?

Race Recon accepts a GPX or FIT file of the race or sportive course, which it uses to identify climbs and inform training and race-day planning.

Are the duration and carbohydrate figures measured or estimated?

They are model estimates for one example rider, not measured ride results or a universal fuelling target; actual duration and needs depend on conditions and execution on the day.

How does Race Recon handle noisy GPS elevation data?

It smooths the raw elevation data before identifying climbs, which reduces the risk of GPS noise turning a steady ascent into a series of misleading ramps.
