Date: Sept. 27, 2026 Participant: Joe Grey-Wilson #11210 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Midrace Surge Fuels a Steady Marathon Effort Joe Grey-Wilson finished the 2026 Boulderthon Marathon in 4:17:57, an overall pace of 9:50 per mile. He opened briskly through the first two miles before a rougher third mile slowed him, then settled into a rhythm through the middle of the course. His strongest stretch came between miles five and nine, where he averaged roughly 9:01 per mile, his fastest sustained running of the day. The final six miles brought a gradual fade, with mile splits stretching past 11:00 before he closed with a quicker final mile back toward downtown Boulder. Grey-Wilson's race unfolded on a marathon course redesigned to cut net elevation gain by about 40 percent, from 982 to 603 feet, and finished, like every Boulderthon distance, on the Pearl Street Mall. Running at altitude above 5,000 feet, his early-race consistency through miles five to nine stands out as the highlight of an otherwise gradually fading second half.
