What is The BIG Swim?
The BIG Swim is a virtual swimming challenge taking place in September 2026. Across the month, 15km your way – or push yourself even further! We’re talking lidos, lakes, pools and more, clear headspace, and that glorious “I did it!” feeling - all while raising money to help people get the support they need to take care of their mental health and wellbeing.
Sign up now to get your free Sport Relief T-Shirt, and raise £200 to get your hands (or head) on your very own Sport Relief Swimming Cap!
Every Splash Counts
Once you’re signed up, don't forget to share your fundraising page with friends, family and far and wide, to get those donations powering your challenge! Remember, if your challenge raises £200, we’ll send you a free Sport Relief Swim Cap – to really make you look the part!
By diving in this September, you’ll be helping to fund vital projects that support the mental health of those who need them most.
£10 could provide two sessions on learning to swim for a woman in need of connection and support.
£25 could provide a week's bus pass for one volunteer to help support local swimming programmes.
£70 could give two women access to a life changing six week learn to swim programme. Building confidence through connection and giving something new a go!
Let’s get swimming - for mental wellbeing, for Comic Relief, and for a big splash of silliness. Thank you for being a good sport!
