Based in Snowdonia, North Wales, Gradient Adventure is a small company run by Glyn Calland.

Originally from S. Yorkshire, Glyn started his outdoor life as a teenager exploring the moors and crags of the Peak District (courtesy of S. Yorks transport subsidies 2 pence bus journeys!). At 16 he joined Castle Mountaineering Club allowing exploration further afield.

While gaining outdoor qualifications Glyn also served in the 3rd Batt. Yorkshire volunteers TA and then 23 SAS Regiment. After working at various outdoor centres in and around the Peak District he started a Sport Science degree in Liverpool and then moved back to Yorkshire. After 2 years Glyn moved to N. Wales to complete a PGCE in Outdoor Education and Biology. He has stayed and has been in N. Wales since 1997.

Glyn is currently a qualified Mountain Instructor (MIA the highest summer qualification for the UK) and also a BCU (British Canoe Union) level 3 coach.

As well as climbing and kayaking Glyn also enjoys windsurfing and has done so across Europe and Australia, instructing in Greece for a season. Glyn is also a keen paraglider pilot and has recently started speedflying.

When not running courses for Gradient Adventure, Glyn works in nearby Local Education Authority Outdoor Centres as a freelance instructor.

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
