David Labouchere OBE

David Labouchere OBE is the managing Partner of optimalFITNESS and co-founder of optimalTRI. A late-comer to triathlon he has qualified for the IMWC in Kona as an age-group athlete four times and raced there three times.

He will help anyone who cares to listen to set really challenging objectives and then to achieve them. He believes in talking the talk but also walking the walk and if you choose to train with optimalTRI expect him to swim, bike or run with you regularly.

Stine Mollebro

Stine Mollebro holds a Master degree in Physical Education & Health Sciences. In addition to her documented professional knowledge, Stine has more than 20 years of personal experience in age group and elite triathlon. She is a Dubai based triathlon coach, a multiple Ironman World Championship qualifier and she has raced Kona.

Stine is the mother of three very young children and believes that one can make dreams into reality with focus, commitment, a healthy attitude and balance in everyday life. She doesn’t just talk about it though; in 2014 she became European Ironman AG champion only 10 months after giving birth.


Having not engaged a professional coach for my first Ironman, OptimalTRI were recommended to me when I began training for my second. Their program was very interactive, their support and encouragement was absolutely first class and the gains that I achieved were beyond my expectations. I will certainly be using OptimalTRI in the future and would highly recommend them to anyone who is looking to achieve their Triathlon goals.

Billy Harkin

Technically thorough, goal orientated and approachable is how I would rate the OptimalTRI team. Each with their own tried and tested experiences and coaching abilities, with OptimalTRI you get the added benefit of an established coaching team and in-house facilities to back it all up.

Robert Marinelli

An ambitious professional coaching team focused on delivering tailored individual triathlon training plans, driving hard where appropriate but allowing flexibility to suite the demands of day to day life of non professional athletes.

OptimalTRI helped me achieve what had previously only been a pipe dream! The team coached, mentored and helped me complete my first Ironman (Nice) in summer 2017. Without their help, experience and know how I would never have been able to achieve this! I would highly recommend them as some of the top coaches in their field in the region!
