Months of trash talking, quad building, 80's montage training in the woods, passive-aggressive tea drinking—it's all come down to this. One hill climb in San Francisco to determine the fastest cyclist on the planet. In this corner, we have Peter Sagan: three-time World Champion, Paris-Roubaix winner, and all around badass. In the opposing corner, we have Grandma Joan: near-centenarian, two knee replacements, pacemaker…and a Specialized Turbo e-bike. Sorry, Peter…the odds aren't looking good for you.
