Date: Sept. 27, 2026 Participant: Cyrus Niamir #13712 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Opening Pace Gives Way Late Cyrus Niamir completed the 2026 Boulderthon Marathon in 4:39:23. He built his race on a consistent front half, holding right around 9:00 per mile through mile 17, before the pace gradually eased over the second half of the course. His standout stretch came early: miles 1 through 17 covered in just over two hours and twenty minutes, a sustained 9:00-per-mile effort across Boulder's rolling backroads out past the reservoir. That opening rhythm carried him deep into the race before the final miles slowed considerably, including the stretch through the lululemon Power-Up Zone near mile 22.5. Building a similar even effort into the closing miles could be a worthwhile focus for his next marathon, given how well the first two-thirds of this one went.
