Mavis Peterson, an 85-year-old from Scotland, just completed a weeks-long journey biking through the countryside for cancer research - and raised almost $74,000.
Granny Mave started her biking challenge at the end of April, starting by pedaling up the west coast of Scotland to Thurso, and then returning to the finish by cruising down the east coast through Fife. And no, she wasn't on an electric bike - she did the whole journey on a traditional cycle.
