Date: Sept. 27, 2026 Participant: Sara Geller #30613 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Strong Start Fades Into a Steady Finish Sara Geller completed the 2026 Boulderthon 10K in 58:33, an overall pace of 9:26 per mile. Geller's race began briskly, with a 8:02 opening mile that was her fastest of the day. She held sub-9:00 pace through the first three miles, reaching the 5K mark in roughly 26 minutes, before easing over the second half of the course. Each mile from four through six ticked slightly slower, closing with a 10:47 final mile. That gradual fade came at altitude, with Boulder sitting above 5,000 feet, a factor worth keeping in mind when setting pacing targets for future starts. If Geller looks to build on this result, holding closer to that early rhythm through the back half could be a worthwhile focus but the strong opening miles were well executed.
