Swimming 50 kilometres across the course of a month might seem a challenge for many, but for Mitch England, that's the norm.
And now he's going to use his usual training schedule to help raise funds for sick kids through the Starlight Children's Foundation's Super Swim campaign.
"Mum asked me if I wanted to do this and I was swimming about 50 kilometres a month anyway, so it worked out well," Mitch said.
"I've got a sign-up at the pool, I'm sharing it on Facebook and dad's got a fundraising bucket at work."
Each training session, Mitch believes he swims roughly 3.5 kilometres and with four sessions a week, that equates to 14 kilometres in a week.
That means that across the course of the month, he could clock up 56 kilometres, which is well and truly above the total he needs to complete his challenge.
The 13-year-old St Stanislaus' College student has been swimming at a high level since he was 10-years-old and has consistently represented the Bathurst City Amateur Swim Club across that time at events such as the NSW Country Championships.

He's currently raised $845 as of Tuesday afternoon, which has him over halfway of his $1500 total.
Mitch is expected to be one of thousands of Australians that will participate in the Super Swim campaign, which will run from January 26 to February 24.
There's no minimum distance requirement, with participants free to swim as far or as little as they want.
The Starlight Children's Foundation was founded by actors Peter Samuelson and Emma Samms in 1982 in Los Angeles, United States, which has since branched out to Canada, Australia and the United Kingdom.
In the past 38 years, it's provided entertainment, education and technology support to more than 60 million children who are critically, chronically or terminally ill.
