My son completed the Midi Vino Fondo yesterday. 86 miles with 6,700 feet of climbing. Riding time was 4 hr. 52 min. Naturally, being both a dad and a grouch, I asked him how many feet of downhill coasting were on the ride.
6.7k of climbing in 86 miles comes out to 78 feet of up and 78 feet of down again per mile. That's a pretty hilly ride. I'm proud of him.
