No, really, it's all in fun. I really don't think that anybody has to be able to run particularly fast. I think endurance is the key. Zombies aren't going to move exceptionally fast, so it's just a matter of continuing on to get ahead of them enough to find a new safe zone.
That's why I am going to focus on a vehicle this summer. I really don't want to try to hoof it unless really needed. I saw a really nice vehicle that I would love to have. I have no idea what this thing was, but it had
three wheels, each about 5 or 7 feet tall, and it was doing about 30mph
through a grass field, smooth as could be, and spreading fertilizer. I know grass fields look smooth, but try taking your average truck through that, and you'll quickly find how rough it is. I tried doing a search on Google, but couldn't find it though.
