Dr Kelly Mackintosh

Kelly is a senior lecturer at Swansea University. Much of her work focuses on the promotion of physical activity and exercise in clinical and hard to reach populations. Whilst much of this stems from their principle motivation, she is mainly interested in the associated energy expenditure and indeed health benefits or implications.

Recent work has strengthened on-going collaborations with Sport Wales, with annual testing for several sports, such as Hockey Wales and Rowing Wales. Kelly’s passion lies in the integration of technology to track exercise behaviours, or performance, and allow real-time feedback for the athlete, coach, or researcher. Her role for 65 Degrees North is to assist in the physiological testing, particularly those surrounding fitness.

Dr Melitta Mcnarry

Melitta is a senior lecturer at Swansea University where she researches the influence of physical activity and exercise training on the cardiometabolic health of paediatric and clinical populations.

With a key focus on the cardiorespiratory response to exercise and its interaction with growth, maturation and disease, Melitta works with national sports teams and governing bodies to develop appropriate training recommendations for performance and long-term health.

Her role for 65 Degrees North is to conduct physiological testing to inform training preparations for upcoming challenges.

Danny Claricoates

Danny joined the Royal Marines in 2003. On completion of training he was drafted to 42 Commando RM just outside of Plymouth and quickly specialised as a Reconnaissance Operator.

Danny deployed to Afghanistan in 2006 for Operation Herrick 5 and it was for actions during this deployment that saw him awarded the Military Cross. Once home and after a second deployment to Norway he was drafted to Stonehouse Barracks, also in Plymouth, to join Brigade Patrol Troop. Danny quickly re-deployed to Afghanistan for Operation Herrick 9 this time with troop being part of the larger Brigade Reconnaissance Force. It was during this tour Danny witnessed an event which, along with events from his first tour, would see him being diagnosed with Post-traumatic stress disorder (PTSD). Danny was medically discharged in 2011.

He now spends his time working on his own business delivering outdoor activities to young people as well as taking part in outdoor freelance work. Danny successfully summited Kilimanjaro in February 2016 and Mt. Vinson in January 2017 with 65 Degrees North and he continues to support the team using his skills and experience gained through these expeditions.

Leesa Harrison

Leesa was provided with the opportunity to become 65DN’s Media Officer, and take up the very privileged position of documenting and sharing every step of the epic World First Record attempt across the Greenland Ice Cap by Peter Bowker and the team, after a chance meeting with expedition lead Rich in December 2013.

She experienced her first expedition when she joined the team for the ‘Conquering Kili’ challenge and documented the emotional journey live from Mount Kilimanjaro. Leesa has accompanied the 65DN team on training packages to the Mont Blanc Massif to photograph and record the team during their training packages for Antarctica, Aconcagua, Denali and Everest. In 2019 she spent 6 weeks at Everest Base Camp documenting the team’s progress to the summit of the World’s highest mountain!

These incredible experiences have given her an appetite for adventure and an even greater desire to support 65DN and help them achieve their objective to inspire and motivate others.
