Participant guide 

In the meantime, here’s some guidance for you.

1. Ensure your details are up to date

Your Swim Pack contains your swim cap, timing tag and kitbag.

If you live in the UK, we will send it to the address saved in your Let’s Do This account, so keep it up to date.

If you live outside of the UK, you will collect it from Marathon House (190 Great Dover Street, London, SE1 4YB) or on Event Day in Hyde Park.

2. Plan your journey to the Start Line

Where possible, we recommend travelling to Hyde Park on foot, by bicycle, or by public transport. A free bike park is available on a first-come-first-served basis.

Participant travel is one of the biggest contributors to carbon emissions at our events, so please use public transport if possible.

To plan your journey to and from Hyde Park, please use TfL.

3. Get to know what is available to you on Event Day

We have a Sensory Calm Space, for anyone who wants to take a moment away from the crowds, and a Multi Faith Prayer Space that is open to all.

If your period falls on Event Day, you can find tampons and pads at the info points and drink stations.

If you have a bladder or bowel condition, a Just Can’t Wait Toilet Card explains you have a medical condition and need urgent access to a toilet. You can download the card, issued by the Bladder and Bowel Community, for free. From that page, you can also purchase a plastic card. There are also bladder pads at the info points and drink stations.

If you are visually impaired, or your disability or medical condition means you need a support swimmer, you can apply for a free place for them. Please email us outlining your request and the reasons for it.

4. Pick your plan

First of all, pick one of our Training Plans and get familiar with the course.

5. Set up your fundraising page

You can sign up to Enthuse, our official fundraising platform. If you don’t have a charity place you can still fundraise for charity!

6. Keep your eye out for the Participant Guide closer to Event Day

We will email your Participant Guide before the event. It includes everything you need to know about getting to the Start Line and more.
