Triathlon and endurance coaching in Cardiff
Endurance coaching for triathletes, runners and swimmers in Cardiff and South Wales, from a qualified triathlon coach and swimming teacher who has raced from sprint distance to Ironman 70.3. Structured, personalised plans with the regular contact that keeps you consistent.

Coaching built around the person, not just the plan
Coaching with ‘be’ is built around the belief that progress comes from understanding the person, not just prescribing exercise. Everyone brings a different background, set of pressures and relationship with fitness, and I take time to listen before setting direction. Empathy, clarity and trust sit at the heart of how I work, allowing coaching to be supportive without losing purpose.
Structure and accountability are central to my approach. Training plans provide direction and clarity, but it is the ongoing support, regular check-ins and shared commitment that help athletes stay consistent over time and reach their competitive goals.
Coached by someone who has done it
I discovered triathlon around ten years ago and have since raced from sprint distance through to middle distance, including Ironman 70.3 Mallorca and the Cotswold 113. My running takes in road and trail races, half marathons in the UK and overseas, and the Greenland Arctic Marathon. I have also taken part in swim-run events, multi-day cycle touring across Scotland and Wales, ski touring in the Alps and mountain ascents including Toubkal and the Welsh Three Peaks.
Having trained for these challenges myself, I understand what it takes, physically and mentally, to prepare for demanding goals: the importance of consistency, patience and adaptability, and how setbacks and competing priorities affect progress.
What coaching includes
- An initial consultation to understand your goals, history, available time and the event you are targeting.
- A periodised plan written for you, adjusted as life and training unfold.
- Regular check-ins and feedback, so you are never training in isolation.
- Technique support across swim, bike and run, including pool sessions where helpful.
- Race preparation: pacing, nutrition basics, taper and race-day logistics for events such as Ironman Wales, Ironman 70.3 Swansea and local sprint races.
Runners and swimmers welcome too
You do not have to be a triathlete. I coach runners preparing for everything from a first 10k to a marathon, and swimmers who want to build confidence and endurance in the pool or open water. If you are not sure which service fits, book a consultation and we will work it out together.

Frequently asked questions
Do I need to have done a triathlon before?
- No. Plenty of athletes come to coaching for their very first event. We will pick a sensible target race and build from where you are now.
Is coaching in person or online?
- Both. Plans and check-ins work remotely, which suits athletes across South Wales and beyond, and in-person sessions in Cardiff are available for technique work and strength training.
Which events can you help me prepare for?
- Anything from a local sprint triathlon or parkrun to Ironman Wales, Ironman 70.3 Swansea, marathons, swim-run and multi-day adventure events. If I have not raced it myself, I will do the homework on the course with you.
How much contact will I have with you?
- Regular. Coaching is about the ongoing support between sessions as much as the plan itself, so you will have scheduled check-ins and a direct line for questions when training does not go to plan.
