Division Champion Closes Strong at Altitude Gabriel Grosz claimed first place in the M75+ division at the 2026 Boulderthon 5K, crossing in 31:31. Racing through downtown Boulder at over 5,000 feet of elevation, Grosz built his effort across the distance, opening with a 10:11 first mile before surging to a 8:59 second mile his fastest of the race. He closed with an 11:13 final mile to secure the division title, finishing 743rd overall among the field of 2,677. The middle mile stood out as the strongest stretch of the race, a full minute-plus faster than his closing mile. That surge through the second mile proved decisive in cementing his position atop the M75+ field, a result worth building on with an eye toward smoothing the transition into the finishing stretch in future efforts.
