Race-morning weather history
Flat Red River Valley course at ~275 m; late-May Fargo swings from near-freezing mornings to summer heat, wind a bigger factor than terrain. 2020 cancelled; 2021 ran Sep 25 (excluded); 2027 is a week+ earlier than the 2024-2026 editions. Wyndo tracks what past editions of the race actually served up at the start hour — temperature, dew point, wind, and rain, and reads the live forecast for the start once race week arrives.
