I like seeing you refer to that as painful since my commute home is 200m of vert in 6km, if I go home efficiently. I feel like a bit less of a wuss for not looking forward to it all the time.
This made me feel better too, since the hill that I complain about (and made Greg & Carol confirm was a big hill) near my house is 600ft up in the first 1.2 miles.
I just spent the summer in a city with approximately 0m (±5m) of vertical in the entire city. Of course, this is 200m up and 200m down in 10k.
