Ultra Cycling Race Weather Forecasts

Get accurate, hour-by-hour weather forecasts for ultra-distance cycling races. Our forecasts are calculated along the entire race route based on the official course profile and typical racing speeds, showing you conditions at every segment of the race.

Whether you're preparing for the Badlands, Transcontinental Race, Atlas Mountain Race, or other ultra endurance events, route-based weather forecasts help you plan your pacing, gear choices, and race strategy.

All forecasts update continuously and include temperature, precipitation, wind speed, and wind direction for each point along the race course.

Why Route-Based Race Weather Matters

Traditional weather forecasts provide point-based predictions that don't account for the unique challenges of ultra-distance cycling races. When you're riding 800+ kilometers through varied terrain, weather conditions can change dramatically throughout your journey.

Our route-based forecasts calculate weather conditions for every kilometer of the race course, taking into account the time you'll likely reach each point based on typical race speeds. This gives you insights like:

  • Temperature and wind conditions at mountain passes during your expected arrival time
  • Precipitation timing aligned with specific route segments
  • Night-time weather conditions for the sections you'll be riding in darkness
  • Headwind vs. tailwind predictions for course planning

Whether you're racing or supporting a rider, having accurate weather predictions for the entire route helps with strategy, nutrition planning, clothing choices, and safety decisions.
