🌊 Join us for a first-of-its-kind event along the Santa Cruz River!
The Río Relay is a unique fun run and volunteer experience designed to bring together communities along the Santa Cruz River in Pima County—while giving back to the river we all love.
Similar to a 5K fun run, the route begins at Juhan Park and ends near Mission Garden. Along the way, teams of two or more will travel through the Santa Cruz Riverbed collecting as much trash as possible within a 3-hour time limit.
⚠️ This is rough terrain, and participants are strongly encouraged to walk rather than run to stay safe and maximize cleanup efforts.
🏃 Participation Options
1️⃣ Participate as a Team Member
Teams will work together in the riverbed to remove litter from the Santa Cruz River.
Entry Fee: $25 per participant
Includes:
✔ 1 raffle ticket
✔ Swag bag
✔ Official race T-shirt
2️⃣ Participate as a Volunteer (Space is limited)
Volunteers will be stationed at one of five trash drop-off sites, where they will:
• Receive trash bags from teams
• Measure and count trash for the trash survey
• Resupply cleanup bags
• Assist with refreshments as needed
Volunteers will receive:
✔ 1 raffle ticket
✔ Volunteer T-shirt
Whether you’re hiking the riverbed or helping behind the scenes, your participation directly supports a cleaner, healthier Santa Cruz River and a stronger connected community.
Come be part of this exciting new tradition—move your body, meet your neighbors, and make a real impact on our river!
