Steady Miles Carry Him Through a Solid 10K Zachary Umansky finished the 2026 Boulderthon 10K in 58:12. His pace held in a tight band across the race, opening with a 9:05 first mile and settling around 9:20 per mile through the middle miles before closing with a 8:58 fifth mile, his fastest of the day. That fifth mile stood out as his most efficient stretch, a small surge before the final mile ticked back up to 9:53. Umansky's race in downtown Boulder unfolded at over 5,000 feet of elevation, a backdrop worth noting given the consistency he maintained across six miles. With little variance mile to mile, there's an opportunity to look at where the third and fourth miles softened slightly and see if a touch more evenness there could sharpen the overall time next time out.
