RunnerCast scores today's conditions for your run — personalized to your preferences, and your tolerance for the elements.
Set your preferred temperature range, wind tolerance, and runner profile. The score adjusts to match the kinds of weather you love (or loathe).
The recommendation considers the next few hours of your running window — so if conditions are improving or getting worse, RunnerCast tells you.
Add your upcoming race or a recurring club run to count down the days and get a forecast for your event so you can be prepared.
RunnerCast pulls live weather data for your location and runs it through a scoring model built around what actually makes a run feel good or miserable. Temperature, wind, precipitation, humidity, and cloud cover are each scored and blended into a single number that drives the Run Now / Maybe Wait recommendation.
The score is tuned to you — set your preferred temperature range, wind tolerance, and runner profile and it adjusts to match how you actually run. The recommendation also looks ahead so you're never caught out by worsening conditions.
RunnerCast also tracks your events, whether it's a race or a recurring club run, and surfaces a forecast for the moment you start. On supported devices, the AI Insight feature turns all of that into plain-language advice — no numbers, no jargon.
