Sehgahunda Trail Marathon, Marathon Relay & Vale of Three Falls

Q: What should I wear for the Sehgahunda Trail Marathon, Marathon Relay & Vale of Three Falls?

Race-day weather in Portageville can swing year over year, so dress for the forecast on the day. As a rule of thumb, dress for ~10°F warmer than the standing temperature once you start running. Layer with a throwaway long-sleeve at the start, gloves and a hat for sub-50°F mornings, and a singlet plus a visor when it climbs above 60°F. The published start time is 7:45 AM.
