Tarrywile Half Marathon

Set in Tarrywile Park, Danbury, Connecticut, the Tarrywile Half Marathon offers three distances—10K, Half Marathon, and Marathon—through rugged park trails. The course is renowned for substantial elevation and technical Northeast single-track sections, delivering views of Danbury and the park’s tranquil lakes. It uses a multi-loop format: one loop for the 10K, two loops for the Half, and four loops for the Marathon, with total elevation gains around 1,500 ft for the 10K and roughly 3,000 ft for the Half (more for the Marathon).

The race is cupless, so runners must carry hydration. Extras include a Ragged Cuts finisher medal, sponsor swag, and a $500 cash bonus for Half winners under specified times. Hikers are welcome for the 10K/Half within a 7-hour limit. Visit the organization's website for the most recent information.
