At 224# and 5' 10", I hate hills. I ride 5 miles early morning and 5 miles evening on the hilly roads in our neighborhood. Takes about 30 minutes.
My wife and I went away for a weekend at a B & B on the Katy Trail and rode 38 miles one day and 20 the morning of the second with no problem since it's nice and level.
Came back home and went for my morning ride. Hills aren't any easier than before I left.
Too bad we just bought this house a year ago. I'd be tempted to move somewhere with level ground.
Okay, done venting. I feel better.
