60km round trip thrice a week. All nice and flat until i have to climb up the castle hill in Heidelberg at the end (switched to an E-Bike because of that)...
The total time for me to get to work with the bike vs taking transit is also slightly higher, but I do make it up in the fact that I get great exercise, and save a little bit on the cost of transit. Plus, listening to podcasts on the bike is a perfect combination for me.
