About Martin 

Martin Rendle is a highly experienced Stand Up Paddler Instructor and Multisport Coach and Trainer with over 30 years experience in the fitness and sports endurance industry.

Based in Norfolk, UK - Martin has been involved in SUP since 2012 after being handed a board and paddle by a friend and told to ‘catch up’ and since then he’s been hooked on SUP!

After this first experience of SUP, Martin decided to enter his first event – a 10 mile (16km) point to point SUP race.  Having just purchased a 11’2” x 32 iSUP he was presented on the start line with a 12’6” x 26” iSUP to race on, then spent the next 2 hours wobbling his way through the course to it’s end – where with aching muscles and slightly scuffed feet (from kneeling a lot due to not being used to a narrow board), he arrived at the finish line with a beaming smile and a want to do more, get involved and really take a bite in to this new and exciting world of SUP!

Since then Martin became an ASI Instructor and then furthered his involvement with the ASI by becoming an ASI School and then an ASI Instructor Training Centre.

Martin founded and operates Norfolk Outdoor Adventures, a Guided Tour and Instruction business in SUP and Kayak located on the stunning Norfolk Broads, UK.  The Norfolk Broads is a 200km protected inland waterway in the east of the country and located very close the beautiful east coast.

Norfolk outdoor Adventures has won various accolades such as Best Tourism Business at the Rural Business Awards 2019, has become a lead experience provider for The National Parks Experience Collection, and has also a finalist in the Norfolk & Suffolk Tourism Awards for Eco-Tourism 2019.
