I'm surprised we have gone this far down this rabbit hole and no one has brought up port-a-johns. Nothing goes down hill quicker than a port-a-john before a race. If you have ever run a marathon or half you know exactly what I am talking about. I do have a pretty active gag reflex and I'll never forget when I went to use one right before the race and I was gaging in there pretty loud I guess because when I came out my DW was rolling on the ground laughing at me. Can't blame her I would have done the same.
