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!
This is your chance to swim a marathon 10K or 1K distance. If you'd prefer, you can take on the marathon 10K challenge as a team of 2.
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
Already have your own place?
If you've purchased a place through the race organiser, you can use it to help end the devastation caused by dementia.
There's no minimum sponsorship target if you've purchased your own place, and we'll be here to support you throughout your challenge.
Want to take on an even bigger challenge?
Across November, take on the Virtual Marathon Swim. Challenge yourself to 10k, 25k, or 50k across 30 days. In a pool or out of doors, this challenge can be done your way in your time. It's free to enter, so why not agree to support us on signup and fundraise alongside? You could support everyone facing a dementia diagnosis.
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:
- £300 for the 10k marathon
- £200 for the 5k marathon
- £150 for the 1k challenge
Rewards
If you've agreed to sign up and swim for us you'll get a branded swim cap to show off in the pool!
Earn your t-shirt and locker/trolley token: if you reach your fundraising target before October 18th, we'll send a t-shirt and if you hit double your target we'll send you a locker/ trolley token keyring out for you to celebrate with! These are sent on a monthly basis.
