It's a 20 mile walk around Boston and having never really walked 20 miles, I'm a little concerned.
Water will be provided but we're pretty on our own for everything else. Has anyone ever done an event like this? Any suggestions?
So far I've heard bring an extra pair of socks and use vaseline to avoid blisters. Any other words of wisdom like that to offer?
Also, what kind of snacks would be smart to pack to eat along the walk?
