possible centry? or maybe 65 miles

[txred9876]

I know this event is strickly cycling but many of you have seen my progress since I started posting back in March/April....

In approximatly one month I will be riding in the Mamma Jamma Ride for Breast Cancer just north of Austin, TX. The ride lengths are 10,25,45,65 and 100 miles.

In may I signed up for 65 miles but can go for more....I did my longest ride last weekend (thus far). I went just over 45 miles. I was tired but with a few minutes rest here or there I probably could have went farther. The route we were doing had many more hills then the route will be doing for our ride. I did the ride at about a 12mph - including the stops (i know still slow...lol) in about 4 hours. If everything came together.... I might be able to do the centry in 8-hours (the longest amount alloted).

Do you think I should just do the 65 and be happy.... do as much as I can to the 100 and have SAG pick me up if I do not make it? Or shoot for the centry?

Any opinions would be great....oh...by the way...I have now lost 44 lbs.
