There are two canals that, depending on which way hounds run, have to be taken on. The dark, murky water with a deceptive cover of green algae looks innocent enough until you miss the opposite bank. One is not jumpable but it does not stop the followers having a go year after year.

The drill beforehand is rather like going through airport security. All mounted followers empty their pockets, and surrender their mobile telephones and valuables to car followers, as there is a high probability that they will go swimming at some stage during the day!
