Based in Snowdonia, North Wales, Gradient Adventure is a small company run by Glyn Calland.
Originally from South Yorkshire, Glyn started his outdoor life as a teenager exploring the moors and crags of the Peak District. At 16 he joined Castle Mountaineering Club allowing exploration further afield.
Glyn currently is a qualified Mountaineering and Climbing Instructor (MCI, the highest summer qualification for the UK) Winter Mountain Leader, and also a British Canoeing Level 3 kayak and Canoe Coach. Glyn also has a Sport Science degree and PGCE in Outdoor Education.
As well as climbing and kayaking Glyn enjoys windsurfing and has done so across Europe and Australia, instructing in Greece for a season. Glyn is also a keen paraglider pilot.
When not running courses for Gradient Adventure, Glyn works for the Joint Service Mountain Training Centre. Glyn will always try to run Gradient Adventure courses personally. In the event of this not being possible Glyn will use other suitably qualified and experienced instructors.
