On Saturday 25 February, swimmers from all around the globe will take the plunge in an attempt to smash the current world record of 2,533 people swimming 100m at the same time with the aim of supporting the End Polio Now campaign.

To achieve this, each participating swimmer needs to complete 100m between noon - 1pm GMT, that’s 9.30pm - 10.30pm local time.

The challenge is to record as many swimmers as possible, all swimming simultaneously, wherever they are in the world, in that one hour.

Tennant Creek Rotary is one of 80-odd clubs around the world participating in achieving the record-breaking swim to help raise funds for the eradication of polio.

Rotary Treasurer, Greg Marlow (pictured), said they need about 25 swimmers to take part in the event locally.

“Entering couldn’t be simpler,” he said.

“All you have to do is swim 100m non-stop within an hour. The Barkly Shire has generously granted use of the local pool, which will be open from 8-11pm,” said Greg.

“There will also be a sausage sizzle for a gold coin donation and any other sponsorship is welcome.”

The brainchild of Grantham Rotary in the UK, the Swimarathon event has also attracted high-profile supporters including Penny Palfrey, Australian ultra-marathon open water swimming world record holder, and Paralympic medallist and five-times World Champion swimmer, Fran Williamson.

Entry fee is $10 per adult and $5 for children under the age 18 with all proceeds going to the End Polio Now 2012 campaign.
