On a training hike I was going farther and with more weight than I ever had before. Thing were going well until I started back down a mountain here in the Seattle area. Searing pain on the side of my left knee. Tendinitis, worse than I've ever had before, reared its ugly head. I start physical therapy in 3 days and will be a 2014'er. Crazy how this works, but glad it happened at home instead of on the trail. Good luck to all you 2013'ers!
