Date: Sept. 27, 2026 Participant: Joaquin Ruiz #11070 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Even Early Pace Gives Way to a Strong Closing Kick Joaquin Ruiz completed the 2026 Boulderthon Marathon in 3:59:19, averaging 9:08 per mile. His fastest mile of the day came early, mile two in 8:01, and he held sub-8:45 pace through the first 18 miles. From there the pace eased into the 9:2010:40 range for several miles before tightening again over the final two miles down to 10:04 and 10:00, closing out a positive-split effort. That late stretch of slower miles lines up with the lululemon Power-Up Zone at mile 22.5, where his splits sat near 10:1510:40 before he pulled the pace back down toward the Pearl Street Mall finish. Running that stretch at Boulder's altitude, over 5,000 feet above sea level, adds real weight to holding pace late, and his rebound over the closing miles showed strong control after the mid-race dip.
