With the Comrades Marathon around the corner, we have to talk about something uncomfortable. There’s nothing worse than being in the midst of a good run and then suddenly knowing it’s time to go — and no, I’m not talking about reaching your destination.

Every runner has, at some point, found themselves nowhere near a loo while the urge to defecate grows stronger with every stride.

If you find yourself in this situation, there’s very little you can do if there isn’t a toilet close by. You simply have to vasbyt in more ways than one.

And if that urge becomes overwhelming, there’s simply no avoiding what comes next.
