New Course Elements for 2023! Featuring Denver Zoo and downtown Denver!
You’ll experience vibrant Colfax with iconic spots like VooDoo Donuts, Irish Snug, and Cathedral Basilica. The new course also takes you by the Capitol, Civic Center Park, 16th Street Mall, Convention Center, stellar Colorado mountain views, and the Cherry Creek Bike Path. While you’re running through downtown, you’ll run through Denver Fire Station #1 and get high-fives by a row of firefighters. This is the only race in the country with a fire station run-through!
New in the Zoo! A runner favorite, the new course keeps the epic mile in Denver Zoo, a once-a-year chance for you to be watched by rhinos, elephants, monkeys, tigers, giraffes, lions, penguins and more. New in 2023 – runners run by the sea lions and sea lion pool, vultures, African artifacts, and a close up of the camels! The Denver Colfax Half Marathon is the only race to run through Denver Zoo! Check out the new 2023 zoo mile!
The homestretch will be running along 17th Street, then 17th Avenue, passing restaurants and historic buildings, before entering Denver’s beautiful City Park for a great after party on the lake with over 20,000 new friends.
