Pace & aid-station chart

Load the race GPX, set a goal time and the aid stations, and get climb-aware splits with arrival times and cutoff buffers. Your file stays in your browser and is never uploaded.

Planning heuristic: each 100 m of climb costs about 1 flat km, each 100 m of descent about 0.2 km, with a gentle late-race fade. It is a starting point, not a prediction. Check the official cutoffs.
