Boulderthon Marathon Chooses HotelPlanner

HotelPlanner, a prominent travel technology platform and hotel reservation engine, today unveiled a new partnership with Boulderthon.

This event has been recognized as one of the Best Fall Marathons by Runner’s World, ranked the fifth-best Half Marathon in the U.S. by Active, the top marathon in Colorado, and one of the “Most Beautiful Marathons in the World” by HalfMarathons.Net.

Offering a full marathon, half marathon, 10K, and 5K, Boulderthon – which will take place on September 29, 2024 – provides a boutique running experience with big-city energy and top-notch amenities tucked away in the world-class foothills of the Rockies. In its inaugural year in 2021, Boulderthon drew in 1600 participants. Fast forward to this year, Boulderthon has solidified its position as Colorado’s premier autumn race series and one of the nation’s fastest-growing marathons. Anticipated to host 10,000 runners hailing from all 50 states and 18 countries, Boulderthon beckons athletes to the scenic running site of Boulder.

“The incredible growth of Boulderthon creates so many opportunities for people across the globe to come together and share their love for running, movement and community here in the beautiful outdoor paradise of Boulder,” says Phil Dumontet, founder of Boulderthon.

“We’re incredibly excited to partner with Boulderthon and this vibrant community coming from all over the world to stunning Colorado,” says Tim Hentschel, Co-founder and CEO of HotelPlanner.

“Marathons push you to your limits. They’re a chance to see what your body and mind are truly capable of, and we are honored to play a part in this journey. To the entire Boulderthon community, welcome to HotelPlanner.”
