Strong Start Fuels Steady Marathon Finish Through Downtown Boulder Alexandra O'Connor completed the 2026 Boulderthon Marathon in 4:25:01. Her opening miles were her best work: she covered the first 7 miles at close to an 8:52 min/mile pace, reaching the midpoint around 1:55:15 still under 9:00 min/mile. From there, the pace eased gradually through the second half, settling into the 11-13 min/mile range over the closing miles as fatigue accumulated, before a final mile push back down to 11:31. Boulder's elevation, over 5,000 feet, adds context to any distance run here, and O'Connor's early miles showed the benefit of a well-paced approach out of the gate. With that foundation already in place, working on sustaining more of that early rhythm into the back half could be a natural next focus.
