Negative Splits Power a Strong Finishing Kick Leilani Harris finished the 2026 Boulderthon 10K in 48:59, an elapsed pace of 7:54 per mile, placing 6th in the F20-24 division. Harris's race built steadily: she opened her first mile at 8:13, settled into the 7:50s-8:00 range through mile four, then surged with a 7:01 mile five her fastest stretch of the race before easing back to 8:20 to close things out. That mid-race mile marked a clear shift in rhythm, showing a well-timed push before the finish. With Boulder sitting above 5,000 feet, holding sub-8:00 pacing for four of six miles reflects a well-managed effort worth building on.
