I asked Joe to coach me for my first full distance Ironman. Prior to the Ironman, I’d only ever completed one full marathon, and had no experience in cycling or swimming (I’d never had a swimming lesson before). I had no clue where to start with swimming and cycling, and started training with Joe across the 3 disciplines.

Not only did I gain lots of confidence in swimming and cycling as a result of the training plans Joe wrote for me weekly, Joe was also able to adapt my training around my knee injury and my demanding job as a teacher. I completed my first ever full distance Ironman in 12 hours and 13 minutes, over an hour quicker than I imagined.

A year ago, I struggled to cycle 80km without stopping or being out of breath- now I’m an Ironman, thanks to Joe’s incredible coaching!

Joe started coaching me around a year ago after a period of time out of triathlon.

I wanted someone to help me regain my fitness but in a way that did not risk injury.
Joe took a steady approach to build fitness gradually working towards some specific goals.

We started off working towards a half marathon and then back into a sprint and then olympic distance triathlon.

I have been super happy with Joe coaching me, we speak regularly about training and goals for the future.

I’m looking to do a couple of 70.3 races and a full distance Ironman next year. We have already spoken about training around work and life and what the mini goals throughout the year should be in the lead up to these events.

When I started working with Joe, I had never run consistently and struggled to complete even 1K without stopping. Just eight months later, thanks to the training plan Joe tailored for me, I ran a marathon and finished with the drive to do more.

His coaching is brilliant, he combines knowledge with a flexible approach that works around my busy life, adjusting sessions for work, travel and other commitments without overwhelming me.

Since then, we’ve focused on improving my 5K and 10K times with pace and heart rate training, and now we’re aiming for the ultimate goal: an Ironman.

With Joe’s support, what once seemed impossible now feels within reach. I couldn’t ask for a better coach.

I cannot recommend Joe and Diablo Endurance highly enough.

Over a nine-month coaching programme, Joe transformed what initially felt like an ambitious aspiration into a reality. Through a carefully structured training plan, expert guidance and unwavering support, he prepared me to complete the 2026 L'Étape du Tour, one of the most demanding amateur cycling events in the world.

What sets Joe apart is his ability to tailor training to the individual. He took the time to understand my strengths, limitations and commitments, building a programme that was both challenging and achievable. His approach combined technical expertise with encouragement and accountability, ensuring that every session had a purpose and every setback became a learning opportunity.

The improvement in my fitness and endurance over the nine months was remarkable. More importantly, Joe gave me the belief that I could tackle a challenge that, at the outset, seemed beyond my reach.

Crossing the finish line of L'Étape du Tour 2026 was an unforgettable moment, and one that would not have been possible without Joe's knowledge, commitment and support throughout the journey.

If you are looking for a coach who genuinely cares about your success and knows how to help you achieve your goals, I would wholeheartedly recommend Joe and Diablo Endurance.
