Cold start — layer up

Runners will start in chilly 32°F conditions — dress in layers for the corral and plan to shed early. Temperatures rising to 42°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. Moderate humidity at 80% is worth noting for effort level, especially in later miles.

About the Roxbury 50K

The Roxbury 50K starts and finishes at Hurlburt Park in Roxbury, Connecticut, on a hilly mix of paved and dirt roads. It begins with a 13.5 mile out-and-back to the Judds Bridge area, then covers five laps of the 3.52 mile Hemlock Loop. The course passes the start and finish lot repeatedly, so runners can reach their own supplies between laps. It runs on the Saturday of race weekend alongside the marathon and half marathon.
