well i did the complete silver comet section starting in symrna and ending 1/2 mile past the alabama line. omg i didnt expect it to be that hard. im used to mountain biking only so i really didnt know what to expect.
first mistake was i took my mountain bike instead of renting a road bike. i averaged 12pmh which was really pushing it over the entire course. in top gear on the flats i could hold 15-16mph without pushing to hard, but it did catch up with me. i was told by a guy on a road bike that he could easily hold 25mph the way his was geared. this would have helped a lot.
either way i now have a good idea of my limits and what to take next time i try it. im happy i completed the silver comet but kinda bumbed i couldnt go the other 33 miles to do the whole thing. i just didnt have anything left and it was starting to get dark when i hit the state line. food and water, i had just enough.
my legs were feeling like they were going to bust open the last 15 miles. i had to get creative to even pedal at that point. instead of a true pedal with my muscles, i had to stand and use my body weight on the pedals to push them down. it was torture, but knowledge gained for the long rides.
i might try it again next fall with a road bike.
i did gps my ride so it feels good to look at it on google earth.
