The Tarrywile Half Marathon, just might be one of the toughest trail half marathons you will ever run. Not only does it have a lot of elevation, a good portion of the terrain is fairly technical Northeast single track. The course offers some amazing viewpoints of Danbury as well as the tranquil lakes in the park. We've got 3 different distances for you: 10K, Half Marathon, and Marathon. Hikers/walkers are welcome for the 10K/half marathon, but must be able to finish within the 7 hour time limit.
Refund Policy: There will no refunds and/or no transfers of your registration or bib to any other person. Entry fees collected are used to develop and produce the event, starting well in advance of the race date--including course preparation, race supplies, permits, and administration.

This in a nutshell is one hell of a course! You can take your best road half marathon time and add 30-45 minutes. Parts of the course are rocky, rooty, and certainly hilly. It is a one loop course for the 10K, two loops for the half marathon and four loops for the marathon utilizing many different types of trails in the park. Total amount of elevation will be 1500’+ for the 10K, 3K+ for the Half Marathon and 6K+ for the Marathon!
You’ve just finished a super challenging one of a kind course! Enjoy your accomplishment, sit back, relax, and don’t forget to cheer on all the runners coming in behind you!
