Over a decade ago, BethAnn Telford received her brain cancer diagnosis after recognizing signs during the Marine Corps Marathon. Feeling a huge pop in her head at mile 19, Telford knew something was wrong. Having to undergo numerous brain surgeries and relearn how to talk and walk, she feared the worst.

The surgeries have left her blind in her left eye, she suffers from seizures so cannot drive, and suffers issues with her bladder. Despite all of this, Telford has been running marathons and will start her 183 miles of running in the World Marathon Challenge, 7 marathons, on 7 different continents in 7 days, in an effort to raise $1 million for the non-profit Accelerate Brain Cancer Cure. 

Telford will be wearing 14 pairs of sneakers designed by pediatric cancer patients, so that when she looks down she can "remember all these kids I have been blessed to come in contact with and know that is what this is all about."
