Competing in the Bridge to Bridge swim is a lot more than the exercise.
"A lot of it for me is the love of the open water," says Margie Chiet, who, at 71, is a Bridge to Bridge veteran. "But I have total respect for our river." She began racing between the bridges in 1997.
"I love being with the other swimmers," says 70-year-old Paddy Gallagher. "We communicate during the year, then the Bridge to Bridge comes up. Sometimes I think I won't do it, but everyone else is ... so I decide to swim."
There was a time when pollution made the swim dangerous, so it went into hiatus from 1967 until 1996, when pressure was put on the Council to reopen the river to swimmers.
"When it was reinstated, that was big," says Margie.
Nine swimmers turned up for training on Sunday, meeting at the Whanganui Multisport Club in Anzac Parade.
"What we're trying to do is keep it going and build it back up again," says Paddy. "The swim is open to everyone — you don't have to be a member of the Multisport Club."
Paddy has been a member, Margie is on the committee and 80-year-old Tony Fantham, a regular swimmer, has also been a committee member.
Markers on the opposite bank are measurements from the Union Boat Club — 1km, 2km or the full length of 3.2km.
The direction of the tide determines when they train, but since they swim in both directions, one way is tougher than the other. They usually swim from the ramp below the club to the rail bridge and back. A portable sign on the bank warns other users that there are swimmers in the water.
The Bridge to Bridge competition is in a downstream direction.
