Enduro

Fasten your seatbelts, the National Enduro is ready to take you on. This high-powered, cross-country race winds like a bad mountain road. Your odometer registers mile after mile of changing weather conditions, shifting gears and squealing brakes - you're passing, always passing. Complete as many of the 99 days as you can. Enduro. Can you endure?
