Steady Early Miles Power a Determined Marathon Finish Sydney Le completed the 2026 Boulderthon Marathon in 4:37:25. She ran a strong opening portion of the race, holding between 9:13 and 9:44 min/mile pace through mile 18, with her fastest mile coming from mile 4 to 5 in 8:56. The second half of the course brought a natural fade, with cumulative pace settling to 10:35 min/mile by the finish as miles 19 through 23 slowed into the 12:17-13:51 range before she rallied over the final three miles, closing in 12:28, 12:24, and 10:03. Le's marathon finished on the Pearl Street Mall in downtown Boulder, a fitting close to a race run at over 5,000 feet of elevation.
