Thanks Alex. I am getting a little concerned about this. It will be a VERY challenging ride, but the 2 who have ridden some or all of this, say the 50 is doable for me. I am a slug on hills, but I just grind it out. I was ride-less this weekend because of a work training I had to attend on Fri and Sat. Today I just needed to sleep in because the class was very intense for me. I did get to enjoy a front row seat of the Key bank building implosion when it was realized I would need to stay the night at the Marriott (I wouldn't be able to get to class on Sat morning if I didn't). I can do a ride next weekend that will incorporate some climbing and then Labor Day weekend I will be gone and again, ride-less. Oh well. I paid for it so I better at least make an effort.
