HALF MARATHON

Welcome to the urban jungle: the all new half marathon through Denver Zoo!



The 13.1 mile half marathon is an all-new course with a wild one mile run through Denver Zoo - including the new Toyota Elephant Passage. The Colfax half marathon is the only race in Denver to go through the zoo! Runners enjoy fast, flat and shady boulevards and the historic homes along Montview and 17th Avenue.
and a run through the open bay doors of Fire Station #1.

Sorry, no spectators in Denver Zoo.

The new course features:

    • 7:00 am corral start time
    • The Denver Zoo Mile takes runners through the new Toyota Elephant Passage
    • Beautiful tree-lined Montview Boulevard 
    • A fun jaunt around Aurora’s City Park and through Aurora Fire Station #1
    • Enjoy the stately homes under the canopy of trees on 17th Avenue
    • The home stretch takes runners back to City Park

The Colfax Marathon is an event that the city goes ape for every year! With the half marathon race snaking through the Denver Zoo, runners will get to enjoy a lion’s share of racing fun in one of Denver’s greatest cultural gems.”
