Representatives from Morebus and Go South Coast are preparing for the Three Peaks Challenge next month.
The group will attempt to climb the highest mountains in Scotland, England and Wales within 24 hours.
The challenge is being undertaken in memory of former managing director Andrew Wickham, who died last year after cancer.
Money raised will support Cancer Research UK.
The event is planned for the weekend of 6 June 2026, close to the anniversary of Andrew Wickham’s death.
