Powering our possible — and medical research — one step at a time together

Join the $1 million pledge to advance life-saving cancer research, powered by one survivor’s mission to run 1,000 half marathons by the 10th anniversary of his own blood stem cell transplant.

Meet cancer survivor Peter Kirk

Watch how Peter found his possible

Run Zero

In just 20 runs over 3 months, Peter progressed from 200m to 42,200m – 211X his “possible!”

Peter went for a short run after the five weeks of slow recovery post-transplant to see how his body would do… and it was not good. After only 200 meters he had to stop. It was in that scary moment he knew he had to do something radical, so he decided to sign up to run the NYC Marathon just two and a half months later. See his progress as he achieved his first goal – the first of many to come.
