Are you KEEN to take on a challenge?

We take part in different fundraising events throughout the year which bring families, supporters, volunteers and anyone new to KEEN together.

International Marathons

Various dates from December 2024

Make your marathon more than challenge, make it a holiday! We have access to marathons across the world from Cardiff to Hawaii, Stockholm to Rome, so don’t worry if you didn’t get your London marathon place! Take a look at these exciting options and raise funds for our very own athletes along the way.
