Kilometre nibbler
I've only done a few audaxes (audices?) and I've heroically saved one small group from getting lost with my superior navigation skills (and GPS). On another I went the wrong way, and a group must have followed me as they whizzed past me while I was stopped wondering if I'd gone wrong. I then realised what had happened, and wondered whether to chase them down and tell them, but they had gone up a gurt big hill so I left them to it. I felt a bit bad about that.
