A team of volunteers in Cumbria has carried out its seventh rescue in as many days.
In the latest incident, on Sunday morning, Wasdale Mountain Rescue Team rescued three men from Scafell Pike.
The majority of rescues in the past week have involved walkers taking part in the three peaks challenge.
At 978m (3,208ft) Scafell is England's highest mountain, and there is concern that those attempting the peak are not adequately prepared.
The Wasdale Mountain Rescue Team said in a statement: "There is a growing concern within our team that these charity type challenge events are becoming more popular and open to many people who would not normally venture onto the hills, particularly at night and in poor conditions."
