Cockermouth Mountain Rescue assisted Keswick Mountain Rescue with a number of incidents.
Other mountain rescue teams were also involved in the incidents.
A spokesperson said: "Penrith Mountain Rescue Team went to deal with a callout above Seatbwaite and we dealt with two others in rapid succession.
"A disorientated party on Grisedale Pike who were unable to find the correct descent in deteriorating weather and a mountain biker who came off and sustained a serious upper arm injury. He was treated and carried down to a land ambulance at Rosthwaite."
