Thanks barba for the advice and encouragement. I'll need to work upto the 30 minute mark though. I kept todays ride short & a little quick (for me) to see where I was. Well I know where I'm starting from and where I'd like to be.
My first short term goal will be to ride for 30 minutes at whatever pace I can. (and get some slicks) I don't know how big of a difference the tires will make, but I'll have a set on by tomorrow!
Thanks again,
