I ride the area shown above by freight train . . . . In little nibble bit rides, 10 miles at a time. Remember, even dwarfs start small. Rode Friday, Saturday and Sunday. Up Taylor Road/Old Rte 40 to Newcastle and back past Trail Head to the house. Brrr is all I can say at 10:00 AM. Gotta give a plug for Jerry at the TrailHead. Stop in for a cup of coffee, it's always good. Anyways, finally pulled up a little lame from the ride this AM driving into work. Just a calf that I felt cramping Sunday. Forget ride your age. You folks are crazy !! Uh, er, it would be a long long ride for me at this stage of my life. Maybe by this summer I can try a 57 miler !!! Would that get one across the Sierra ?? Finally made it up Indian Hill Road, Newcastle, with a friend hectoring me. Any of you remember starting out and the effort it took to climb what seemed like endless hills ?? LOLZ.
Re: The Diablo elevation profile; I will have nightmares of that tonight. That's 3x or 4x my level right now.
