Breathe Team, Valencia Marathon 2026
Fundraising for Valencia Marathon 2026
Billy Chapman
Hi friends and family!
I’m running with the Breathe Team again for the 2026 Valencia Marathon, alongside my lifelong friend Leo Leighton, who’s joining me in fundraising as well. Together, we’re aiming to raise a combined $3,000 for Cystic Fibrosis Foundation research.
We’re running in honor of my beautiful wife, Sea, who has Cystic Fibrosis and lives every day with incredible courage, strength, and grace. Watching her navigate challenges related to CF that most of us never have to think about is a constant reminder of why this cause means so much. I’m honored to lace up again for the Breathe Team, and even more excited that this will be Leo’s Breathe Team debut (and 2nd marathon!).
Thank you so much for supporting us. Every donation truly makes a difference, and Leo and I promise to run hard for every single dollar raised.
Let's go!
