I ride either rail trails, single track or on the road. I say that I'm 1 year into this after a 25 year break from bike riding. It's a calendar year but really only a few months of actual riding.

Anyway I do very little single track. Most of my riding is rail trail or road and since road is so convenient that is what I do during the week. I have a 8 mile loop that has a number of fairly large hills, the entire 8 miles has 900-1000 feet of climbing depending on the exact route. I rode it today after a week off from riding and no problems. The thing is even 2 months ago I couldn't ride the whole thing without walking up at least 1 hill but now no problems. 61 years old.

Up until a few weeks ago my trail/single track bike was my Trek 4500 which is actually a hybred. I use that for anything other than road. My road bike is my 1986 Asian steel bike I did a few upgrades but nothing radical. I purchased a $300 Craigs List Cannondale that is now my main road bike. My classic steel will be my back up road bike, my wife's old mid 80s bike will become my rail trail bike. So I have 4 bikes now all with different applications.
