One day after one of my evening rides on the local MUT, my wife watched as I carried my bike up the 3 flights of stairs to our apartment. Laughing she said, "I'll be that's the hardest part of your ride - carrying your bike back up to the apartment." And thinking about it, she was right.
I'm sure most of us have a "typical" ride we do whether it be a daily commute or trail ride or whatever. So, what is the most difficult part of your "typical" ride?
