Ultramarathon Weather Planning

Weather at every aid station, based on your actual race pace.

For an ultramarathon, knowing today's weather isn't enough. You need to know what the weather will be at mile 67 when you arrive at 2am, and at mile 134 when afternoon storms typically build. MyWeather.Space's GPX Timetable feature does exactly that — upload your race GPX, set your pace for each segment, and get weather conditions at every aid station at your estimated arrival time.

GPX Race Timetable

• Per-segment pacing — set different speeds for each section (downhill faster, technical climbs slower)
• Rest time at each aid station — accounts for crew stops and drop bag time
• Exact arrival weather — temperature, wind, precip at the hour you arrive
• Night segment detection — 🌙 flags segments you'll run in the dark
• Temperature range per segment — min/max temps you'll experience between aid stations
• Storm alerts — red flags when storms are forecast at your arrival time

Elevation Profiles

Upload a GPX file with named course segments and get a full elevation profile for each section — distance, gain, loss and high point. Great for race briefings or crew planning. Works with Bigfoot 200, Western States, Hardrock 100 and any race that provides a GPX course file.

MyWeather.Space is free to use. No account required. Upload any GPX file from CalTopo, Gaia GPS, Strava or your GPS watch.
