I encountered my very first hill today. It was massive and I wasn't expecting it! I went to the lowest gear and climbed maybe half of it sitting, then I had to climb out of the saddle for the remainder of it. The top of a hill has never been so sweet! It was a hard climb seeing as it was my first, and I don't think I'll be attempting it again until I've trained on smaller hills first. My left knee is really hurting and I think it's due to the massive climb. I've been riding for over a week with a two day rest and haven't had any knee pain other than this. I definitely pushed it too hard and probably should have just turned around and rode down the hill, but I didn't want to give up!
