Think Big Trail Challenge
The Think Big Trail Challenge is a trail running event on October 4, 2026 in South Williamsport, PA, held on the Williamsport Water Authority trails. The event offers two distances.
The courses combine smooth singletrack, rugged climbs, and flowing descents with historic and scenic sections. Key trail segments include the Pocowanache Trail, which features steeper climbs, rocky terrain, and winding descents, and the Bluebird Trail, a forested section with gentle inclines that leads to the finish. The route passes the historic Remington Ruins and crosses the Green Bridge.
Course routing:
- 10K
- 5K
The 5K begins on a gravel road, follows Remington Road and Shuler Woods Road, climbs Shelterwood Trail, crosses the Green Bridge, then follows the Aqueduct Trail into the Bluebird Trail to the finish. The 10K follows the 5K route and then continues up Remington Road onto the Pocowanache Trail for a challenging ascent to a vista before returning to the 5K finish via the Green Bridge and Bluebird Trail.
There will be one aid station at the Green Bridge serving both distances. Awards are given by gender and age groups including 15 and under, 16-19, and then 10-year age groups up to 60+ for both distances. Special commemorative awards and cash prizes are designated for the 15 and under 10K and 5K champions.
Proceeds benefit the Think Big Pediatric Cancer Fund. Registration pricing shows early and later tiers and race day registration is available; swag is guaranteed for the first 200 registrants. Registration closes on September 26 at 11:59 PM ET. Visit the organization's website for the most recent information.
