Date: Sept. 27, 2026 Participant: Les Csorba #11888 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Front Half Gives Way to a Hard-Earned Finish Les Csorba covered the Boulderthon Marathon in 4:34:10, finishing 5th in the M 60-64 division. His race was built on a strong, consistent front half through 14 miles he held a cumulative pace between 9:04 and 9:23 per mile, with the opening mile his fastest of the day at 9:04. That stretch from mile 1 to mile 14 stands as the most efficient running of his race, holding tightly within a 20-second pace band despite the rolling nature of the course. The back half told a different story, with cumulative pace drifting from 9:32 at mile 15 to 10:27 by the finish as the effort compounded over the closing miles. Racing at over 5,000 feet of elevation, Csorba passed through the lululemon Power-Up Zone near mile 22.5 en route to the Pearl Street Mall finish, a stretch where his split slowed to 14:17 as fatigue set in late. Considering the strength of his first 14 miles, targeting a touch more reserve for the closing miles could help him carry that early rhythm further into future races.
