Chicago Marathon & Team Roo Runner Spotlight: Rena!!!! For Rena, one thought made joining Team Roo an easy yes: “The thought of anyone having to choose between vet bills or their dog’s health is truly heartbreaking to me.” Her own dog, Penny, is healthy but she runs for every pet and parent who has had to face that impossible choice. For her, every mile is about making sure families can say “yes” to more time and more memories. Rena, thank you for your heart and your determination. Chicago will be brighter with you out there and we can't wait to cheer you on along the way!!!!! 🧡 #chicagomarathon #chicagomarathon2025 #chicagodogs #petcancerawareness #runningforacause
