Run for Sea-Changers

You may be a weekend jogger or a long distance runner. You may fancy running a coastal trail, clambering over inflatables or pounding the pavement. Whatever you fancy, we have some great challenges for you.

With locations all around the UK, we're sure you'll find an event that will suit you. We would love you to take the challenge and dive in to a Sea-Changers fundraiser this year….run for our seas.

To help you find the race of your dreams we're working with two great organisations who can help you start your fundraising journey - Endurance Life and Run for Charity.

For information about how we can support you download our Fundraising Pack.

Or you can contact us directly for help, advice and information.
