Shaunna Burke just finished the Everest Marathon—yeah, the world’s highest one—while battling stage four breast cancer. She powered through chemo, surgeries, and still managed to crush 26 miles at 17,000+ feet, finishing fourth in her category! The craziest part? She trained by running to her hospital appointments. Talk about unstoppable. She’s already eyeing bigger mountains next. If you need a dose of inspiration today, this is it. #EverestMarathon #CancerWarrior #Inspiration #Health
