I did 86 miles today in Harriman Park, NY. That's a new long for me and I'm happy I was able to keep up my usual pace of 10 mph. It's not very fast but it's the best I can do up there with all the hills and my type bike. I'm also including in the time the breaks I needed, which were many. For one thing, I had to stop and exercise my feet a few times as there was pain in the balls of the feet. I guess it's from my spiky pedals and from standing a lot going up hills. Luckily, no lasting issues. I sure got a great- and really long- workout!
