The Highland Cross is the main event in Tuesday's edition of The Adventure Show, along with some great rock climbing on Shetland.
The Highland Cross involves a run and bike ride from coast to coast across highland Scotland. I filmed in the transition from run to bike at the head of the glorious Glen Affric.
The programme will be broadcast Tuesday 11th November on BBC-2 Scotland and you can find that channel at the top of the electronic programme guide on Freesat, Sky and Virgin Media. It will also be on the iPlayer for 30 days.
