You are more than welcome to swim in as many organised Swimathon sessions as you wish over the event weekend. For each swim you wish to do, you will need to create a new registration, paying the entry fee for each place. Make sure to log out of your first registration before creating your second one. You can do this by clicking your name in the top bar. We then suggest that you only use one of your fundraising pages when sending your link out for sponsorship. You can mention in your 'personal message' that you are taking on more than one challenge.

If your local venue is not an option on the search list, the venue has not yet registered to host sessions in 2026. However, if they know that there are swimmers interested in joining at their venue, they may wish to do so. We recommend heading to the pool to let them know there is interest in their local area and they can still get in touch with us and register to host in 2026.

If they cannot host, this may be due to timetable clashes or staffing requirements. But you can still join! We recommend the ‘MySwimathon’ option, where you can swim anywhere, anytime between 1 March - 31 March 2026 – you would need to attend the venue during standard recreational hours and track your own results to submit online. So, there are options available to you if your venue does not register to host a session at their pool.

Swimathon will take place on Friday 20 – Sunday 22 March 2026 and the more flexible MySwimathon version will take place between Sunday 1 March and Tuesday 31 March 2026.

Swimathon is designed to be inclusive and accessible. This is your swim. Distances range from 500m to the Triple 5k, there is a Swimathon challenge for you! The blue ribband event is the Swimathon 5k. We’ve consolidated all Challenge types for you to read more here

Swimathon takes place on the weekend of 20- 22 March 2026. Venues across the country have signed up to host sessions throughout the weekend, for you to complete your specific Swimathon challenge at. You can meet other swimmers taking on Swimathon and all join together to complete your distances. Medals will be awarded at the session following your swim and your venue will submit your swim times to us.

MySwimathon runs from 1 March - 31 March 2026, overlapping Swimathon weekend.

This option allows you to swim in your own time, wherever suits you, and submit your own results. This is useful if you don’t live near a venue hosting a session or aren’t able to join any hosted session times near you. It also suits if you prefer to swim independently, not in a Swimathon session!

To complete your MySwimathon challenge, simply head to a swimming venue during open hours, and book in as per their preferred method for recreational swimmers. You keep track of your distance and time, and then log that into your Swimmer dashboard to submit your results! Medals will be posted out once they are submitted.

The below figures are based on a 25m pool:

Triple 5k > 9.37 Miles > 600 Lengths

Swimathon 5k > 3.1 Miles > 200 Lengths

2.5k > 1.6 Miles > 100 Lengths

1.5k > 0.9 Miles > 60 Lengths

500m > 0.3 Miles > 20 Lengths

Swimathon is held in over 450 pools across the UK. Visit our Venues page to check out where these pools are and to find your closest one.

If you can’t make the Swimathon weekend (20-22 March 2026), a pool isn’t close enough to you, or if you just fancy a bit more flexibility to your Swimathon challenge, take advantage of MySwimathon. This entry option allows you to swim any distance (one of the set challenges or make up your own), any time and at any venue of your choosing between Sunday 1 March - Tuesday 31 March 2026.

Please note if you enter under MySwimathon the leisure centre you wish to swim at will charge you to enter the pool.

For MySwimathon Challenges, this is only limited by the bookings you make at your venues during their recreational hours.

For Venue-Hosted sessions, most venues host a 3-hour session for swimmers to complete their distances, some may be able to offer more time, and some may be restricted to less time - so look out for this when selecting your session so you know how long you have to complete.

Venue-Hosted session times are set by the venues and may be limited due to staffing or other bookings they have in place. If you require longer than the specified session time, we recommend speaking directly to your venue to arrange that.

Teams can be made up of 2-5 people. Only one swimmer is allowed in the pool at any one time. You can split the distances up in any way you wish.

Swimathon welcomes all ages and abilities.* It doesn’t matter if you can swim one length or one thousand, Swimathon has the challenge for you!

* Under 16s must be entered and accompanied by an adult.

We allow swim aids to ensure our challenges are inclusive to all swimmer abilities. However we recommend getting in touch with the venue directly to see if they have any limitations on the specific type of swimming aid used, as you will be sharing the lane with other swimmers completing Swimathon.

The great thing about Swimathon is that you don't even have to get wet to get involved! Many pools require volunteers to help register swimmers, log laps, record times, support and encourage their swimmers. Click here to find out about our volunteer programme.

If you can aim to arrive at your sessions half an hour before the swim time so you have enough time to get changed and be ready to swim at the start of the session time. For example, if your sessions is 8am-11am, you will start swimming at 8am.

All swimmers will receive a medal for completing their challenge. Those taking part in an organised Swimathon session will receive their medal immediately after successfully completing their swim. Those taking part in MySwimathon will be sent a medal via post after meeting the fundraising criteria and uploading their challenge time online.

Please note, Swimathon 5k medals will only be given to those who complete the individual Swimathon 5k challenge.

If you are taking part in the Triple 5k challenge, you’ll receive 3 x Swimathon 5k medals

All swimmers will need a cap to wear when taking on their challenge to help the lap counters count your laps.

Those taking part in MySwimathon will not receive a cap unless purchased.

All swimmers will be able to download their personal certificates from their dashboard after the event.
