Event Summary

Almost 1.2 million runners, joggers, walkers and spectators of all ages have gathered over the years to create a spectacle that defies description. Olympic medal winners and hopefuls, grandmothers and kids, running enthusiasts and one-race-a-year guests from all over the world come together at the foot of the Rocky Mountains to form one of the sport’s truly unique events. Each year we host 50,000+ participants and 100,000+ spectators throughout the course for what we like to call the biggest and best Memorial Day celebration on earth. After you cross our finish line, we want you to feel “I AM BOLDER” in your heart and soul.

This year, Let Me Be Your Lungs has two whole teams of athletes participating from National Jewish Health and St Joes. They are running in honor of their patients they care for. Check out their efforts here!
