Run for Austin’s Lungs is a family-friendly 5K walk/run held in honor of baby Austin, who is bravely battling chronic lung disease. Join us to celebrate his first birthday, raise awareness of his Chronic Lung disease, and support his ongoing medical care. Every step taken helps give Austin the breath of a brighter future.

The entire registration fee (minus the $4 processing fee) goes directly to Austin’s care. After you register, the site will ask if you’d like to make an additional donation—this can simply be left at $0, meaning your total charge will be $54 for race registration.

If you’d prefer to support Austin without registering for the race, you can do so by selecting the Donate button instead of Sign Up.

Join us on October 11, 2026 for the Clo Cow Half Marathon, 10K & 5K in charming Historic Downtown Petaluma! Wind your way through picturesque Sonoma County farmland and rolling hills, where friendly sheep, horses—and of course Moo-Cows—will cheer you on every step of the way. Sure, those climbs are a challenge, but the sweeping country views at the top are well worth the effort!
