The Spring Thaw

Be a Part of History The winter's first big race is back for its 50th 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 participate in its 50th running on February 28, 2026. 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! ALL RACES BEGIN AT 10:00 AM and EVERYONE GETS SOUP!
