A pair of nude cyclists who were spotted riding a tandem bike in the Lake District have revealed the reasons for their 'cheeky' bike ride. The couple caused quite a stir when reports came in on social media that a naked couple were riding through Windermere, Bowness and Ambleside on Saturday. The pair have now revealed themselves to be Colin Unsworth, 54, from Bolton and Sadie Tann, 34, from Sheffield, who call themselves the Free Wilders.

Both naturists and naturalists, Colin teaches mushroom foraging and runs the UK's largest mushroom Facebook group called Forest Horizons whilst Sadie is a full-time student of environmental biology. Colin, who has two grown-up children, said: "Each year we take on a challenge to raise money for good causes which includes both bike rides and walks. "This year, we chose the Lakes which is a very special place to me.

I've been camping here since I was five and it was home from home for my kids as they grew up. "We wanted to raise money for two important causes important which are Rewilding Britain and MIND. "Having a connection to nature is so important, not only for the mental and physical health benefits but also for the future of the human race essentially.

"I also chose MIND as I'm not afraid to say that a few years ago I went through a very bad period which included a relationship breakdown. For around 18 months I was suicidal. "You feel that you can't reach out to anyone even though there are people to talk to, so it's important to raise.
