About this race
Event Overview
The 2026 Run With The Deer Flies 25K, 15K, and 8K will be held on Sunday, July 26, 2026. Three distances to choose from, including the 8K that was added last year. This proved to be a popular addition for new trail runners as well as those who would like a shorter distance.
Location
We are looking forward to returning to Camp Seph Mack near Penn Run, PA and hope to see you there. The Deer Fly is directed by trail runners for trail runners.
Course Description
The Deer Fly is a fun and challenging trail race with a mix of single-track trails, pipeline roads, swamps, hills, and creek crossings. Aid stations approximately every four miles, but carrying water is strongly recommended. Post-race Bona's Pizza compliments of Steve Pagano.
Beneficiaries
The Deer Fly benefits Indiana County Parks & Trails and Citizens' Ambulance Service.
