Event Information

The Think Big Trail Challenge takes place in South Williamsport, Pennsylvania. The event offers 5K and 10K courses.

Course Details

The 5K course starts on a gravel road before heading onto Remington Road. Runners take a right onto Shuler Woods Rd, then a left onto Shelterwood Trail for a hill climb. After descending, runners take a right up Remington Road and cross the Green Bridge. They then take a quick left onto the Aqueduct Trail, which transitions into the Bluebird Trail at the historic Remington Ruins. The course finishes on the Bluebird Trail.

The 10K course follows the 5K route but extends further. After the initial section, runners continue up Remington Road and take a right onto the Pocowanache Trail. This section includes a challenging ascent to a vista. Runners descend the other side of the trail and return to Remington Road. A right turn onto the Green Bridge reconnects with the 5K route, finishing on the Bluebird Trail.

Both courses use trails such as the Bluebird Trail, Pocowanache Trail, Shelterwood Trail, and Aqueduct Trail. They feature a mix of gravel roads, singletrack, rolling terrain, climbs, and descents. There is one aid station at the Green Bridge for all participants.

Additional Details

Parking is limited, and carpooling is encouraged. Race day registration is available. Awards are given for first place (male and female) in several age groups for both distances. The first 200 registrants are guaranteed race swag; any remaining swag is available on a first-come, first-served basis.
