My Mighty Marathon will run for 26 days. You can do a mile a day, or do it all at once, so long as you complete your personal marathon by 26 January. And as for what you do, well you can skip, walk the dog, swim, skateboard, unicycle - whatever you want so long as you complete your own Mighty Marathon!

By taking part you'll be promoting a healthy lifestyle, showing how keeping fit doesn't have to be a big commitment, spending time with others and raising money for Sea Cadets. The means we can keep on having a positive impact on the lives of young people all around the country.

The money you raise helps us to offer a whole world of activities to children and teenagers from all kinds of backgrounds.

From sailing or rowing, to engineering and mountain biking, we'll do our bit to keep our cadets active while they gain experience and qualifications along the way. Giving them a head start in life and supporting them over the finish line in everything they do.
