[MENTION=456320]CMBravo[/MENTION] - Welcome!

I do think that a 75 mile ride the month after you got your first road bike would be premature. It was a pretty nice gesture on the part of the person who offered it, though. I'd ask for a rain check for some time this summer. It's good to have a goal to work towards, that way you can plan your rides to gradually work up to it. Finding a club would help in that, you'd have folks to advise you as you progress, and to ride with as well.

Remember - the rubber side goes down.
