I thought this was a good thread to resurrect
Currently I drive part of the way to work, park up in a little village and cycle the rest of the way. Here's my cycle into work:
As you can see, it's up and down at the start, then downhill at the end. Despite going over 30mph on that hill in the primary position (it's a 30mph zone in a residential area) I am still overtaken on occasion...
I take a slightly different route home, the hill I now climb is adjacent to the one I ride down. Just better to cycle up in evening rush hour (conversely, not good to cycle down in rush hour....)
As you can see, a fair bit of climbing for me
