Bio

Ross Mumbles Triathlon
I completed my first full distance triathlon in 2017. Since then, I’ve fallen in love with the world of triathlon and endurance sports. What keeps me hooked is that the effort you put in is what you get out — a principle that rings true in every event I’ve taken on.

When I started, I was a complete rookie. Since then, I’ve come a long way, training alongside some of the best British professionals in the sport. I’ve experienced first-hand what it takes to cross the finish line of your first full IRONMAN. And I’ve felt the drive to push beyond that — striving for qualification for Kona and other World Championship events.

Future Plans

Over the past six years, I’ve been steadily building this coaching business with a clear focus: to offer real coaching. For me, that goes far beyond just handing out a training plan. It’s about sharing knowledge, experience, and insight with those who truly want to learn and grow. There’s nothing that makes me prouder than seeing an athlete make a smart decision in a race or key session, based on something they’ve picked up during our work together.

Optimal Endurance has grown into something with real depth. We’ve introduced a club feature to bring people together, for training, racing, and more. We now have five coaches (and counting) working with a wide range of 1-to-1 athletes. They come from all backgrounds and are chasing all sorts of challenges: marathons, ultras, triathlons, and even self-made, unique endurance events.

My plan is to continue to grow the team, business and base in the authentic and organic way as it has over the last 2-3 years.

TESTIMONIALS

MIKE

Channel Swimmer
"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."

AMY

Long Distance Triathlete
"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"
Dom Olympic Park

DOM

Runner & Triathlete
"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"

FRANCISC

Long Distance Triathlete
"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."
Russell Running

RUSSELL

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

KATIE

"In 2021 I worked with Optimal Endurance to complete a full distance IRONMAN in Tallin. The training was focused, 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. If you want to improve across Swim/Bike/Run this is the team for you."
