This summer dive into a marathon like no other

This is your challenge, so it's completely up to you how often you swim to complete your chosen distance! 

To help you decide, our friends at Outdoor Swimmer have put together some guidance with suggested weekly distances, based on your experience, as well as top tips for making your Swim Marathon fun and achievable. 

Check out the guidance from Outdoor Swimmer

However, you decide to reach your distance, just make sure you're being realistic for your level of fitness – and stay safe! 

Use an app 

Download an app like Strava to track your swims. You can either link this to a waterproof smartwatch if you have one or manually add an activity every time you swim. If you use Strava, you can link this directly to your fundraising page, log your swim distance and keep your sponsors up to date with your progress. 

On your fundraising page 

If you don’t use Strava you can still log your distance using a manual feature on your fundraising page. This helps track your progress and keeps your sponsors up to date with how you’re getting on. 

Keep your records offline 

Prefer to use a good old-fashioned pen and paper? Use our downloadable distance tracker  to make notes of all your swims, then update your fundraising page to let your sponsors know where you’re at with your challenge. 

However you choose to track your swim challenge, make sure to share your progress with your friends and family!

Join our Strava Club to meet fellow Swim Marathon participants, and our Swim Marathon Facebook Group, where we regularly share support and expert advice. It’s also a great space to share your personal Swim Marathon journey, or find support and guidance from fellow swimmers.

If you've decided you're taking on an outdoor Swim Marathon challenge, then our friends over at Outdoor Swimmer have loads of useful tips and advice on swimming outdoors, such as their guides on where to swim, and how to get started.
