Well lets see...according to my running log my 102.1 miles took me 16 hours, 57 minutes and 38 seconds

I dont track my stroller minutes as its usually walk 1/4 mile - stop to retrieve item tossed out of stroller, walk 1/4 mile - stop because dd wants to walk. walk slowly 200 feet, let her back in, walk 1/4 mile...let her back out..OH we are at the park....then walk 1/4 mile......you get the picture..

So in actual TIME my 25 miles of strollering ALONE may have taken MORE than your 31 hours!

According to my running log, 109.3 miles took me 21 hours, 36 minutes, and 7 seconds!
