Race-morning weather history
Mid-February Austin swings from near-freezing to warm/muggy (typical start ~55F at 89% humidity, highs to 77F) — late waves and 7-hour finishers can hit afternoon warmth. 2021 marathon cancelled (COVID). Sponsor churn means historical results index under at least five names. 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.
