Strong Start Fades Late in Solid 5K Finish Cooper Tennison crossed the line in 25:32, placing 262nd overall and 198th among men out of the field of 2,677 in the 2026 Boulderthon 5K. Tennison built an early edge, running his opening mile in 7:48 before surging to a 7:17 second mile, his fastest stretch of the race. The final mile slowed to 9:33, pushing his overall pace to 8:14 per mile as he finished the race on the Pearl Street Mall in downtown Boulder. A steadier effort through that closing stretch could help him carry his mid-race pace all the way to the finish next time.
