Consistent Pacing Pays Off with Late Surge Russ Vandenberg maintained a steady pace throughout the Boulderthon Half Marathon, with split paces fluctuating modestly between 8:04 and 8:32 minutes per mile for the first 11 miles. An interesting highlight is the late race burst during the ninth mile, clocking in at an impressive 6:21. However, mile 10 saw a slowdown to 10:33, an area to examine for improved recovery and endurance in future races. Despite some fluctuations, Russ's overall elapsed time was 1:49:13, yielding an average pace of 8:20 min/mile. Evident in your consistent pacing is an opportunity to harness that strong ninth mile and perhaps push for earlier acceleration in future races. Finishing as 145th in the M30-34 division, with 802nd overall out of 6546 participants, underscores a solid performance amidst a competitive field. Focus on maintaining and evenly distributing energy throughout the race to optimize performance further.
