Course Map and Relay Exchange Points

The starting line will be in the same general location, but runners will head south instead of north into Littleton. The finish line is in the Pirate’s Cove Waterpark parking lot near Belleview Park in Englewood.  The address is 1225 W Belleview Ave, Englewood, CO 80120.

The relay will consist of three legs of roughly 5.8 miles, 4.3 miles and 3 miles.

The first and second relay exchange points will be in the same location in 2022. The relay exchange zone will be at approximately mile 5.8 and 10.1. The location is after the runners cross the river and turn right across from the Regal River Point & RPX movie theater.  The theater parking lot is across the street from the exchange point.  There will be an aid station and portable toilets there along with a timing mat at the exchange point.

The runner coming into the exchange point will be wearing the belt with the timing tag. He or she will cross the timing mat before handing the belt off to the next runner. Teams are responsible for their own transportation to and from the starting line and exchange zone. Please park as close to the bike path as possible and take caution crossing Platte River Dr.
