Steady Early Pace Gives Way to a Hard-Fought Closing Stretch Michael Tesalona finished the marathon in 4:26:40. He ran the first ten miles in even fashion, holding between 8:39 and 9:25 per mile and reaching the 10-mile mark in 1:30:04. That rhythm carried through halfway, with mile-to-mile pace staying inside a tight 9:009:50 band through mile 20. The final 10K told a different story, as splits stretched into the 1215 minute range before he closed with an 11:17 last mile back into downtown Boulder. The opening ten miles stand out as his strongest stretch, averaging exactly 9:00 per mile without a single split slower than 9:25. That consistency built a solid foundation before the course's later miles, which pass the lululemon Power-Up Zone near mile 22.5, tested his closing legs at over 5,000 feet of altitude.
