In at the Deep End 2020

Join Olympic swimmer Mark Foster and hundreds of other amazing people at the Olympic Lake in Eton for our first ever Swimming Challenge.

Choose to swim either a 2.2km (one full length), 5km (one complete lap) or 10km (two complete laps) course on this famous lake to raise vital funds and awareness of Regain Sports Tetraplegics Charity.

Through the charity’s incredible work, we’ll be helping countless people who have become paralysed in a sporting accident regain their independence.

We also have a specially designed 1km course for tetraplegic participants, who will be supported by Mark Foster and some other celebrity swimmers.

Deemed the best Olympic rowing venue by Denise Oswald (IOC member and FISA President), the Dorney Lake in Eton makes a brilliant location for our epic swimming challenge. But fear not – you don’t need to be an Olympic athlete to take part. People from all currents of life are welcome, as we come together for tetraplegics.

Kicking off the event with some vibrant entertainment, motivational speeches and an energised warm-up, you'll be buoyed up and raring to go by the time you start your swim.

Kitted with your In at the Deep End swim hat and time tag, we'll track your time - but it's not a race. Go at your own pace and enjoy the electric atmosphere!

We'll have a team of trained first-aiders, swimming specialists, life guards and medical support ready to help you out if needed.

Once you cross that beautiful finish line, we'll give you your In at the Deep End 2020 medal and feed the shark's appetite you've worked up with a tasty free meal and drink.

Help people regain their independence
The best part of this challenge is that it’s all for Regain Sports Charity. Regain is the only charitable organisation dedicated to improving the lives of people who have become tetraplegic in a sporting accident.

One minute these individuals are fit, active and healthy; the next they are paralysed and in need of support for the rest of their lives. Regain helps these people to regain their independence and get back into sport after their accident. Because Regain is a small charity with a very specific cause, your funds will go a long way into helping them carry out their work.

Places for our first ever swimming challenge are likely to go faster than Mark Foster himself, so please register early to secure your place.

Are you tetraplegic?
Tetraplegics are more than welcome to join the challenge. We'll have a separate course for you, specifically tailored to tetraplegics to ensure your safety.

If you're tetraplegic, please get in touch with Regain to arrange this. The best way is to email the charity at or visit their website here.
