Thanks all for your feedback. Just finished back to back centuries this weekend fully loaded with gear and feel great. I had some serious headwinds yesterday on the last 40 miles and also had them for the first 20 miles today which I feel was good training. I averaged approx 14mph both today and yesterday and which allowed for plenty of rest/food stops and it left me with 3+ hours of daylight left in the day.
I know I'm pushing it by trying to accomplish 100+ miles per day but I feel that unless I have severe weather for multiple days or major mechanical failure I should be able to make it. I fully understand that this trip will not allow for the typical sightseeing that one might desire nor will it allow for much rest. It's more of a physical challenge/test for me plus I get to take 11 days away from responsibility
Thanks again for all of your help!
