Dress for ~10°F warmer than the standing temperature once you start running. Throwaway long-sleeve at the start, gloves and a hat for sub-50°F mornings, singlet plus visor when it climbs above 60°F. The race-day forecast above is the source of truth closer to the date.

No published deadline. Most races raise the entry fee in tiers and can sell out without warning — sign up early if you're committed.
