Nearly Four Minutes Faster Than Last Year Luca Marcondes Mangini, 8, of Boulder, CO, finished the 5K in 31:05, a sizable improvement over his 34:59 from the 2025 Boulderthon. Luca opened with a 10:05 first mile before surging to an 8:53 second mile, his fastest stretch of the race. He eased back over the final mile, closing in 11:07 for a 10:01 overall pace. That mid-race push through mile two, run at elevation above 5,000 feet in Boulder, stood out as the strongest segment of his race and helped set up his improved finish compared to last year's effort.
