Two rescue teams went to the aid of a walker attempting the Coast to Coast Walk after he injured himself.
The man was on Greenup Edge, on the section between Borrowdale and Grasmere, when he slipped and heard a snap in his ankle.
The walker managed to find a mobile phone signal and called for help.
Keswick Mountain Rescue Team was called out about 2.15pm on Sunday.
A team spokesperson said: “As Keswick team were short on numbers, help from the Cockermouth team was requested.
“In hot and muggy conditions both teams made their way up from Stonethwaite and after an assessment of the casualty there was a long stretcher carry back down to the vehicles.
“From our Keswick base transport was made available for a transfer to the Cumberland Infirmary in Carlisle.
“Many thanks for the support from the Cockermouth team.”
The incident lasted just over 5¼ hours and involved 10 Keswick team members.
The previous day, its volunteers were called out to an injured walker on High Seat.
A group of three men were descending the fell towards Ashness Bridge when one of them slipped and injured his ankle and was unable to continue.
The spokesperson said: “Two Keswick team vehicles made their way up the forestry road on the north end of Thirlmere to gain as much height as possible followed by an off-piste slog up and over High Seat to meet the casualty a few hundred metres down the other side.
“After assessing and splinting the ankle the casualty was carried and hauled back over the ridge to the vehicles overlooking Thirlmere, and then taken back to his accommodation in Keswick.”
The incident involved 17 team members for just over three hours.
