S-Curve at the top of Prospect Hill
This afternoon I walked up and down the hill on Prospect Road between Columbia Pike to Marietta Pike in western Lancaster County. After riding thirty years in 37 countries and descending miles-long hills all over the world, it was on this short, steep descent south toward Columbia Pike that I went the fastest I have ever ridden: 59.5 mph.
It is the right kind of hill to go fast. Although the hill is short, it is steepest and straight at the bottom. Other times I have been over 55mph it is always on hills that have a 15% or more grade near the bottom of the hill. Prospect Road is 16% at the steepest point. But the other factor in going 59mph was the S-Curve at the top and the 1980s Bronco that passed me on the way into the turn.
The big, old Ford SUV has the aerodynamic profile of a brick so when he went past, I pedaled like crazy to stay near him. He had to slow in the second turn so I could stay with him. As we exited the turn, he stomped the gas and pulled away. If he stayed anywhere near the legal speed, I would have to be on the brakes. But he went way over the 35mph speed limit so could get sucked along in his draft. I could hear the spokes sing, so I knew I was flying.
When I stopped, the max speed indicator in my computer said 59.5 mph. At this point, it looks like a lifetime record. I have descended miles-long hills in the Alps, the Pyrenees, the Rockies, the Berkshires, Israel, the Republic of Georgia, and in Macedonia. But length does not matter for max speed, only grade percentage and wind direction--and a good draft.
