The Spring Thaw

The winter's first big race is back for its 51st incredible year. The Spring Thaw is the longest continuously run race in Pennsylvania, and you get to be a part of that history when you sign up! The Spring Thaw starts and finishes at North Park's iconic boathouse and follows counterclockwise loops around the lake with 5, 10, 15, and 20 mile race options. This race is a great training/test event for the 2026 Pittsburgh Marathon or any other spring race! Race Start - all distances - 10:00am. Course closes at 2pm.
