Race-morning weather history
Early-July Atlanta: hot and humid, typically ~72F at the 7am start rising toward upper-80s, high dewpoints — a recurring heat-risk race; typical-climate characterization, UNVERIFIED; ERA5 supplies actuals. 2020 CANCELLED as an in-person event (COVID; a virtual/rescheduled Thanksgiving-timed substitute was floated). 2021 ran July 3–4 as a two-day, capacity-limited edition (anomaly). The deterministic July-4 slot still holds for climatology; 2020 had no in-person race and 2021 was split across Jul 3–4. 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 the race confirms its schedule and race week arrives.
