Thirteen-year-old Arnold Prichenfried has cycled 100 miles, all in laps around Brockwell Park, to raise money for the Maudsley Charity.
The Charter School North Dulwich pupil, who is in year 8, completed 58 laps over the course of a week.
He has now smashed his initial £150 target – with more than £700 on his JustGiving page at the end of last week.
“I chose the Maudsley Charity because even before the Coronavirus it was hard for people to get the right help, so now that the NHS overall is so busy it must be even harder.
“I got the idea out of nowhere. I just thought that I don’t really use my bike much so I thought that this would be the perfect way to stay active.
“While I was doing it I felt really happy, so it taught me a lesson that giving to others can make you feel really proud.
“I feel that mental health is such a covered-up issue that isn’t talked freely about and it is also something that we are all very likely to experience – whether it is a family member’s death, to being bullied – it all adds up.
“It is best to learn about how to handle it from a young age.”
