Well I did 20 miles sunday,(in about an hour, wow for me), through old dundalk, then my penninsula,northpoint blvd route (kept close to home as I don't have a back up tube or CO2 pump yet) really not bad on the road bike, the hills that took some out of me on the 1.5" tires on my commuter were nothing compared to 25c tires, riding position also is so much more back friendly, I even rigged on lights to my helmet and bike so I can take this to work tommorow. I hope next saturday I can try to go further.
