Firefighters based at Leyburn Fire Station will take part in the December Ascender challenge tomorrow to raise money for the Firefighters Charity.
The crew has an hour to climb up a ladder as many times as possible.
Firefighters across the country are taking part in the challenge with teams competing to see who can ascend the most times.
Leyburn firefighters will take part in the challenge at 2pm on Saturday at Leyburn Fire Station.
Everyone is welcome to attend to support the crew.
