Join us for our seventh annual run in the woods! Last year we had a great event nd we are looking to make 2018 even bigger and better! You can challenge yourself with 26.2, 13.1 or 6.55 miles! With a mix of pavement (just a little), forest roads, wide and single track trail, this run has it all--beautiful canopied forest roads, riverbank single track, and fast, flat woods running.

Hillsborough River State Park--one of the state's oldest--provides great facilities for an awesome start/finish area and our post-race buffet.

Racers will get emailed a pass to secure their entry to the park on race morning.
