I'm riding my first 600K this weekend. My plan is to ride the 400, sleep for 3 hours and then ride the 200. Had a good 400 (also my first) a couple weeks ago. Finished in 20 hours, at least good time for me. We will see how it goes. I've put in the work, lost the weight and upped the fitness. Packing some pain managers like Ibo, Tylan, lidocaine, Deep Blue,zip locks to hold ice for my "Farmers Back. Hoping the left knee holds out. I've done the planning, but I know at some point in time, it will be gut-check time. I'll give it my best shot.
