Strong Start Fuels a Top-Tier Finish Natalie Hennessy finished the Boulderthon marathon in 3:29:14, placing 99th overall and 10th among women in the field. She opened fast, banking a 6:19 first mile and holding sub-7:30 elapsed pace through mile 20, before slowing through the mid-20s with splits stretching past 10 minutes between miles 21 and 24, then closing the final two miles in the 8:20s. Her strongest sustained stretch came over the first ten miles, run at a 7:05 elapsed pace despite Boulder's elevation above 5,000 feet. That effort carried her past the lululemon Power-Up Zone near mile 22.5 as her legs eased, a well-timed lift before she rallied for the run into the Pearl Street Mall finish.
