Date: Sept. 27, 2026 Participant: Mallory Ringbom #32315 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Steady Start Fuels a Strong 10K Finish Mallory Ringbom finished the 2026 Boulderthon 10K in 54:13. Her second mile was her strongest stretch, clocking 7:58 and dropping her cumulative pace to 8:04 per mile, the fastest point of her race. From there, each mile ticked slightly slower, with her final mile settling at 9:54, bringing her overall pace to 8:44 per mile by the finish. Ringbom's race unfolded as a gradual fade from a brisk opening pace, a common pattern in races that begin fast and settle into a sustainable rhythm. Her early miles suggest strong initial fitness, and with the finish coming after a climb in elevation from downtown Boulder, sitting over 5,000 feet, there's a solid foundation here. A touch more even pacing across the back half could help her carry that early speed further next time.
