Ok - thanks a lot.
I expect I will get the 30 miles done in a little over 2 hours - I did 20 today in 1 hour and 17 minutes. I do usually ride about 2 - 3 hours after lunch, and drink lots of water all the time. I'll just toss a bananna in my bag and see if I need it. This will be my longest ride yet, and I'd like it to stay fun.
Thanks again!
