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 with Dream Challenges.

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.

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.

The Swim

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.

Please go to the In at the Deep End 2020 event page here for the full details and to book your place.  Places are likely to go faster than Mark Foster himself, so please register early to secure your place.
