The time estimates apply published temperature–performance curves to this race's ten-year weather history. Performance peaks at an effective race temperature of roughly 40 to 50°F and degrades faster the warmer it gets and the slower you run (Ely et al., 2007; El Helou et al., 2012). Wind adds a cost that grows with the square of the wind speed (Pugh, 1971), split into head and tail components on point-to-point courses. Shorter races are penalised less. This is a model, not a prediction; your training and the course matter more.

Over 2016 to 2025 the start averaged 49°F (9°C) (feels like 44°F (7°C)) with 78% humidity and 7 mph wind, warming to about 51°F (11°C) by the finish. It rained measurably on 3 of those 10 race days. The coldest start was 40°F (4°C) in 2022; the warmest was 59°F (15°C) in 2016.
For a typical 49°F (9°C) start: Long Sleeve Tech Shirt, Capris or Light Tights, Running Cap, Waterproof Jacket. Dress for about 15°F warmer than the start temperature, since the race itself adds that much, and plan to shed anything you only need in the corral.
