Date: Sept. 27, 2026 Participant: Ian Dunning Crawford #10339 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Fast Front Half Gives Way to a Grinding Finish Ian Dunning Crawford completed the marathon in 3:57:32, an average pace of 9:03 per mile. He ran the first 13 miles in roughly 7:37 pace, holding that rhythm through the middle miles before pace gradually eased in the second half and slipped further over the final six miles. Mile 11 stood out as his fastest full mile, covered in 7:17, part of a strong opening stretch that carried him through downtown Boulder's early miles at over 5,000 feet of elevation. His pace loosened noticeably approaching the lululemon Power-Up Zone near mile 22.5, with splits lengthening from there to the finish on the Pearl Street Mall. A useful focus going forward could be sustaining that early rhythm deeper into the back half of the course.
