The challenge

Marathon Swims is a one-day open pool swimming event staged at London Aquatics Centre, on Queen Elizabeth Olympic Park. Take on the ultimate swimming challenge at an amazing location!

When you swim for us, you'll receive:

  • a support pack with fundraising help and materials
  • access to a Facebook group where you can chat to other swimmers
  • support from our dedicated events team to help you smash your fundraising target
  • the knowledge you're making a difference for everyone living with dementia

Fundraising

You'll receive a welcome pack with fundraising help and materials as well as support from our dedicated events team to help you achieve your goals.

The targets for charity place entries are to be confirmed. 

FAQs

The event organisers are responsible for allocating start waves. If you wish to speak with them about this, we suggest you contact them directly. 

Yes you can! Spectators can pay for a Poolside Access pass or register for a free spectator pass (no poolside access). The free spectator passes will be launched later in the year. 

Anyone wanting to spectate who has not registered, they will need to access the building via the main centre reception.

A JustGiving page is the easiest way to fundraise and share your story. You can easily share your page with your friends, family and colleagues on social media and email, plus everything happens automatically.

The money you donate is sent to us, Gift Aid collected, and your sponsors thanked. Job done!

If you’re collecting money on a JustGiving page, there’s nothing you need to do, your sponsorship comes directly to us.

If you have collected any cash, you can bank it and pay in using one of these options: 

  • Pay the donations directly onto your JustGiving page if you have one.
  • Send a cheque made payable to Alzheimer’s Society to Alzheimer’s Society, Suite 2, First Floor East Wing, Plumer House, Tailyour Road, Plymouth, PL6 5FS. Please include our paying in form so we have your event details.
  • Pay over the phone with a credit or debit card. Call our lovely Supporter Care team on 0300 222 5808.
