Testimonials

"5 years and still going, in that time I have progressed on all fronts. This year I took on my first full distance IRONMAN in Copenhagen. The planning of training around my work/life and adjustments meant I was able to stand on the start line fit and healthy and execute a race way beyond what I thought was achievable.."

"A wealth of knowledge and expertise to tap into - whether it was on nutrition, kit, physio, feeling etc. it was there and it was always accurate and top quality. If you’re looking to up your game and don’t know what will help the most, this is where it’s at!"

"We have worked together for 12 months. The big goal for 2024 was performing in Hawaii for the IRONMAN World Champs. The experience and attention to detail on the specifics of the race were amazing!! I have improved across swim/bike & Run, I have also got alot stronger in the gym with some specific focus. I can't wait to get stuck into 2025 and beyond"

"In 2021 I worked with Optimal Endurance to complete a full distance IRONMAN in Tallin. The training was focused on the specific event, I had a clear plan on race day and I finished in 10hr 53mins!! I enjoyed the process of translating my running background to triathlon training. If you want to improve across Swim/Bike/Run this is the team for you. Thank you"

"I had an amazing experience at the Mallorca Triathlon Camp 2026!
Everything was very well organised from start to finish, which made it easy to FOCUS fully on training and recovery - SPA included! "

"OE and my coach Jack Rees are AMAZING! I have been working with them for about 18 months now and in that time I have achieved things that I would never have thought to be possible beforehand."

"I have been coached by coach Finn for over 2 years now and have seen an improvement in performance within a range of events from the 1,500m up to Half-marathon, as well as solid preparation for my first 70.3 triathlon."

"Outstanding Mallorca Triathlon Training camp with some great people. Hats off to the coaches Ross, Brett, Finn & Simon for putting on such a quality week - can’t recommend enough!"

"NYC Marathon with Paulina and OE. It was my first marathon and notoriously a tough course. I had only run two halves before, and wasn’t sure if full coaching was right for a near ‘beginner’. But the whole experience was brilliant"

"I’ve been a member of the OE club since 2025. The structured weekly sessions, coach input, and supportive community have made a big difference to my motivation and consistency — particularly the Tuesday rides.'

"We worked together in 2020 and 2021 in my build up to swimming the channel successfully in Aug 2022. A unique goal that Ross has helped with from setting my training to coming on the support boat."

"Ross has coached me for over 5 years to run my fastest 10k, half, marathon (2:58), 70.3 and full distance (10hrs 28mins). Any goal I have my training leads me to surpass my expectations"

"Ross and I have largely been working together to improve my marathon time particularly for London, but I've also PB'd in the 10k and half marathon too. Training is varied and specific to me"

"Ross’s knowledge and experience allows him to tailor specific training plans to suit the individual needs and end goal(s). He is always open to suggestions and works collaboratively with you to achieve the best possible result."

"I’ve thoroughly enjoyed working with Ross for almost 12 months. He’s always willing to relay his vast experiences around training and racing. The sessions are always personal and specific to my targets and Ross is always approachable with answers to my questions or with adaptations to fit in with everyday life. Whenever I have raced I have gone in feeling prepared and armed with a detailed race plan which includes a nutrition plan. I’m thrilled with what I have achieved and look forward to progressing further under Ross’ supervision."

"Ross has a wealth of knowledge and experience that he has been sharing with me over the past few years. Whether it be understanding the training plan specifics, race day plans, nutrition or managing a time starved athlete, he tailors the approach to your every need! I’ve always struggled with injury as training load builds but I’ve been relatively unscathed for the past couple of years under Ross's watchful eye, I’m also the fittest I’ve ever been! I'd put an enormous amount of trust in Ross no matter what your goal or starting level is."
