Question of the Day: Your Longest Walk

I know that this is a tough question to answer – because it could mean any number of things. I mean, I’ve been to Disney World a number of times, and my husband tends to have us racing from one side of the park to another to beat the biggest lines – so I have had some days where I walked so very much.
If we’re talking about longest recorded walks, it was definitely during my half marathon training process (and the half marathons themselves). But probably my longest mix of recorded and unrecorded was the day of the Queen Bee Half Marathon, when we walked to the starting line, walked the entire half marathon, walked around the post-race party, then spent a ridiculous amount of time walking around the city of Cincinnati, trying to find the car back. (Just for the record, it turned out that it was surprisingly close to where we’d left the post-race party.)
What about you? How far was your longest walk?
