Theodore's Heart Initiative is an official charity partner of El Tour de Tucson. Every mile ridden and every dollar raised helps us build the technology needed to catch heart defects before a baby's first breath.
Partnering With El Tour de Tucson
El Tour de Tucson is one of the largest cycling events in the country, with routes ranging from a family 1-mile ride to the full 102-mile Perimeter Century. Since 1983, it has helped nonprofits raise over $138 million for causes across our community, and this year we're honored to join as an official charity partner, riding and fundraising alongside our neighbors.

We kicked off our El Tour season at the Pima County Loop de Loop this past weekend as an official charity partner. We spoke with so many fantastic folks, met Olive the desert tortoise, and enjoyed the live music while inviting cyclists to ride with us in November.
