There is nothing else like it in Tucson~a running relay on The Loop. 

What's the "Loop"?

The Chuck Huckelberry Loop is 120+ miles of paved, shared-use paths that connect the Rillito, Santa Cruz, and Pantano River Parks with the Julian Wash and Harrison Road Greenways. However, in 2025, due to the ongoing Sunset bridge construction, the RAT will utilize the Rillito and Canyon Del Oro Washes. The RunAround Tucson will use 50 miles of the Loop and its segment partners.  View the map to see the event's course.

How Does the Relay Work?

This is a supported relay race with Nine Exchanges (10 running legs (12 if using the "unofficial" exchanges on Legs 5 and 9)).

The relay Starts and Finishes at Rillito Park.  Distances between the Exchanges vary from 2.75 miles to 7 miles.

What Constitutes a "Team"?

The minimum number allowed on a team is two, and the maximum number is ten (or 12 if you are using the unoffiicial exhanges on Legs 5 and 9).

Teammate One starts from Rillito Park and runs east to Exchange 1, where he/she will check in with the Event Time Keeper, and then hand off to Teammate Two to begin his/her run to Exchange 2, and so forth. You MUST check in at every Exchange, even if you have less than 10 runners on a team. If your team does not check in at every Exchange, your team will be considered a DNF and will be ineligible of a team award. This does not include the Ultra Loopy Runners, who only have to check in at Exchange 6 (Steam Pump Ranch). 


All teams must be done and off the course by 6:30 p.m. (Slowest teams have 11.5 hours to complete the course. That's an average of 12:30 minutes per mile.)

All Teams must arrive at Exchange 5 (La Cholla dirt lot) no later than 1:15 p.m. 

All Teams must arrive at Exchange 8 (La Cholla dirt lot) no later than 4:30 p.m.

Each team is responsible for getting their teammates to the Exchanges and back to the Start/Finish line to celebrate.
