There is some controversy about the environmental impact of the Three Peaks Challenge. In an editorial in the British Mountaineering Council's Summit magazine, Jill Hudson argues that the Three Peaks Challenge should be shunned as it costs charities more to clean up after participants than they raise by taking part. In 2011, Wanderlust magazine placed the challenge on a list of destinations in need of greater care, and that the numbers of participants should be limited. Organisers disagree, arguing that the 30,000 participants in the Three Peaks Challenge is small compared to the 250,000 who climb Snowdon annually. Since March 2010, the Fundraising Standards Board has acted as a centralised hub for complaints from the National Parks about groups engaged in the National Three Peaks Challenge.
