I have done this! I am on day 57 now of "fake" commuting. I actually have taken up mountain biking during this time because riding on the MUP/bike lane from my house to work and back every morning sounds kinda boring. I live really near a really legit MTB park so I have been riding in to it at about 6am, riding up to the top of the hill and back down the other side, then home again.

I may incorporate these newfound mountain bike trails in to a few commute detours per week when this is all over, then we'll find out if I can do the same climbs and steep rock rolls and rocky descents with a laptop on my back!
