Surviving a 5K

Tonight, I am attending an annual 5K that our business joins every year.  Many corporations in Orlando join in.  The first year I did it, I ran.  Then I thought I should walk.  I found that you can not walk at this.  The walkers are extremely slow.  They usually are 6 wide.  They make it really difficult to pass.  The following year, I ran.  I started more towards the back of the pack.  Although I was not fast, I was not as slow as the walkers.  Yesterday, we had a meeting about it.  I asked "What do we do if the Walkers attack us?".  One person just stared at me.  The person next to her asked the person "do you watch the Walking Dead?".  Answer No.  If you don't, the zombies on the show are referred to as Walkers.
