Use only human powered vehicles for 230 hours.
I initially underestimated how long 230 hours was (I think Heather and I briefly talked about this one and somehow I still didn't think it was that long.)
Made it harder by accidentally choosing to do this in a heat wave, still manageable but it required some extra planning.
I did 22 miles on foot and 52 on a bike. Made it to: 2 grocery store trips, 3 concerts, 1 doctor's appointment, a bike repair appointment (yes, should have done this first but it was fun to see how fast I could run back up the hill to my house), and 1 time to volunteer.
