Hey John, just saw this thread and if you are going for your pr, I would say that you will have to hold just under your AT HR. Since you have added on the 1.1 mile to the 8000ft top, it will be an hour plus ride, something like 1;10 or so I would guess. We just had a guy here from Capetown SA, and he did that ride last week. I only mention that because usually it is all covered in snow this time of year, but we had a great 10 day heat wave, so all the roads are clear with snow on the sides. I think your old time for the regular mountain climb was in the mid 57+ range, and that was when you were 50. So now that you are in the 55+ AG, what do you think you can hold??
