The first and second relay exchange points will be in the same location in 2022. The relay exchange zone will be at approximately mile 4.7 and 8.4. 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.
