The Queen has granted permission for an event supporting veterans to be held at Balmoral Castle again this summer.
On June 23, teams will tackle the challenging countryside around the royal residence to raise money for charity Walking With The Wounded.
Participants will race across one of several routes through the wilderness, ranging from nine to 24 miles, by orienteering using a map and checkpoints.
Each group will have the opportunity to walk with ex-military personnel who have previously been helped by the charity, which supports vulnerable veterans with physical or mental injuries, or social issues such as homelessness, to access better care and get back into employment.
The Balmoral Challenge was held for the first time last year and raised more than £100,000 for the organisation.
Three routes have been selected.
The shortest is a nine-mile foray exploring the cairns in the forest above the castle.
