We are Action Challenge and take groups, individuals, charities and companies on inspirational adventures & challenge events. Our events are usually unforgettable, sometimes life changing, and always rewarding with group camaraderie as important as physical commitment. Take part in one of our challenges and fundraise for a charity - or just do it for yourself. Our events have helped to raise over £50 million for a range of UK charities.
