Final 40 Finishers Celebration Presented by lululemon.

We’re excited to introduce a brand-new tradition at Boulderthon for 2025: the Final 40 Finishers, Presented by lululemon!

This initiative was designed to embrace the inclusivity of our sport and celebrate every runner's journey and dedication, regardless of pace. The last 40 timed finishers of our Full Marathon will be rewarded with a full lululemon VIP post-race experience including a curated lululemon gift, recovery lounge, massages, and buffet. 

It’s the ideal place to relax, enjoy some refreshments, and celebrate your remarkable accomplishment.

At Boulderthon, we believe in inclusivity and honoring the determination of all runners, and this is our way of showing that every finish line is worth celebrating.

Due to City and County permitting, our course must be reopened to traffic 6 hours after the start of the race and 4 hours after the last finisher crosses the finish line. Our Support and Gear Vehicle (SAG Wagon) will be there to assist any runners needing a ride or help to complete the race in time. You'll still receive your finisher's time and medal, even if you need a little boost along the way.

For our 5K and 10K races, we've set a 6-hour time limit to ensure a safe and enjoyable experience for all participants.

Thank you for being part of Boulderthon and helping to create a race that’s all about community, spirit, and celebrating every step of the journey. See you at the finish line!
