Consistent Start, Minor Deceleration Ali Zirille from Denver competed in the 2025 Boulderthon 5K, maintaining a steady pace in the initial stages of the race. Her first mile was completed in 9:13, placing her 329th overall and 21st in her division. She showed slight acceleration in the second mile with a 9:02 split, though her overall rank shifted to 375th. The final mile saw a deceleration, with a split time of 9:59 and an elapsed overall pace of 9:28 min/mile, putting her 382nd overall. Ali ranked 27th in her division, which is commendable.
