Steady Early Pace Gives Way to a Gritty Closing Stretch Joe Cospito completed the 2026 Boulderthon Marathon in 4:23:44, an average pace of 10:03 per mile. Cospito ran the opening miles briskly, reaching mile 10 in 1:33:38 and holding a cumulative pace near 9:20 per mile through the halfway point. Miles 11 through 18 stayed consistent in the 9:00-9:50 range, keeping his overall pace tight. The final 10K told a different story: from mile 20 to the finish, his per-mile splits climbed steadily from 10:21 to 12:40, a notable slowdown after a well-controlled first two-thirds of the race. Still, his strongest single mile came early, mile 11, covered in 8:20. Racing at Boulder's altitude of over 5,000 feet, Cospito passed the lululemon Power-Up Zone near mile 22.5 before finishing on the Pearl Street Mall in downtown Boulder.
