Date: Sept. 27, 2026 Participant: Carlierianne Lalo #13302 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Early Pace Fuels a Steady Marathon Finish Carlierianne Lalo covered the marathon in 4:28:23. She built an early cushion through the first nine miles, holding between 9:05 and 9:20 per mile, then eased pace gradually through the middle miles before tightening back up over the final stretch closing with an 11:14 split into mile 25 followed by a 9:34 mile 26, one of her fastest of the day. That first nine-mile stretch stands out as the race's strongest sustained running, anchoring her overall time. Boulder sits above 5,000 feet, a backdrop to any marathon effort here. Her mile 22 split, clocked at 11:38, would have carried her past the lululemon Power-Up Zone near that point on course. The race, like all Boulderthon distances, finished on the historic Pearl Street Mall in downtown Boulder.
