USA Today has named Boulderthon’s 5K as the 5th best in the United States, while simultaneously announcing its half marathon as the 8th best in the US, in its 2024 10 Best Readers’ Choice awards.
The lists are curated by USA Today editors reviewing thousands of races across the USA, narrowing it down to the top 20 in each category by a panel of expert runners, and then voted on by readers to determine the winners.
“With Boulderthon still being such a young event, it is a huge honour to already be gaining this national recognition for not only one, but two of our courses,” said Phil Dumontet, founder and President of Boulderthon.
“To see Boulderthon’s name on these lists next to veteran races is truly exceptional, and it speaks to the incredible work by our team and partners to build a world-class marathon in the stunning running mecca of Boulder. Since day one, we have always prioritized the runner experience first and foremost, and we are incredibly grateful to see our team’s, partners’, and stakeholders’ efforts recognized.”
The fourth annual Boulderthon race series is taking place on September 29, 2024, and will feature a marathon, half marathon, 10K, 5K and Kids Run. The marathon and half marathon will once again have their start and finish lines located in downtown Boulder.
Along the course, participants can take in views of the Flatirons, as well as Boulder Reservoir, Table Mountain and Haystack Mountain along their way. The course features relatively limited elevation change (384 feet for the half marathon, and 982 feet for the full) and multiple straightaways, making for faster than might be expected race day performances.
The nearly flat 10K course will run participants through the streets of Boulder showcasing the scenic town, before leading them to Downtown Boulder for the finish at Pearl Street Mall. Boulderthon will also be debuting a new fast 5K, as a flat all-roads course at the 2024 event.
