Date: Sept. 27, 2026 Participant: Keira Marshall #41181 Race: 2026 Boulderthon 5K Distance: 3.1 miles

Strong Middle Mile Powers Solid 5K Finish Keira Marshall completed the 2026 Boulderthon 5K in 30:46, an average pace of 9:55 per mile. Marshall's race shape was a classic pyramid: a 10:21 opening mile, a sharp drop to 8:28 for the second mile, then a settling to 10:59 to close things out. That middle mile stands out as the highlight of the race, roughly two minutes faster than either mile flanking it. Given that Boulder sits at over 5,000 feet of elevation, holding that pace through the middle stretch reflects well on her effort. A touch more evenness between the first and third miles could help smooth out the overall pacing in a future race, though the middle-mile surge shows real strength to build on.
