Hello, I'm new to the board.
I live 2.2 miles from work, and today I rode my bike in for the first time.
My biggest concern was riding alongside traffic, which was astoundingly not an issue at all. The motorists were incredibly accomodating, mostly avoiding the right lane where I stayed.
That said, I think I need a new route. I tried to take a back way in, which is actually the shortest route. It includes one heck of a hill, though.
From my house, I go way down to a river, use a small bridge, then go up back to street level. The hill going back up to street level (ironically, downtown), is a killer. I got about 1/2 way up riding when I realized that there was no way I could go all the way, so I stopped and walked the bike up the rest of the way. This is partially because I'm overweight and haven't biked regularly since i was in shape and in college.
I looked at a map, and I found a new way, which will add about a mile but has more gradual hills. I bet I end up less sweaty at work with this longer route.
