What my triathlon clients say..


“A very eye opening experience as to how I should fuel my body. Learned a lot and it translated into being fitter on the pitch and playing better”

– Daniel, 26 Performance Nutrition

“John’s guidance has made a huge difference to my performance both in training and on the field. My energy levels are in a much better place which is down to changes in both my nutrition and lifestyle. What I liked most about working with John was how simple he made the process for me. Each week, we set small, manageable goals for me to achieve and it really added up after the 12 weeks. I have had a few once-off consultations with different nutritionists in the past who were very knowledgeable and provided a good service but in hindsight having lots of dietary changes thrown at me all at once felt a bit overwhelming and it was for this reason why I usually quit after a few weeks. The weekly check-ins with John made everything much more attainable for me”.

– Sean, 23 Performance nutrition

“Prior to working with John I was having a lot of stomach discomfort during my runs. I got to the stage where I was eating very little or avoiding food altogether before my runs. This left me with less energy and my training dipped as a result. John guided me on what foods to eat, how much to eat and the timing of them also. I now know exactly what works for me and what doesn’t work for me. Since working with John my training has improved a lot and I no longer have the stomach discomfort. I also just set a new PB in the Cork city Marathon!”

– David, 36 Performance Nutrition

“My best year yet! A new PB in both the Dublin and Cork Marathons. I have never felt as fit. Thank you John”

-Juliana, 31, Performance Nutrition

Let’s improve your triathlon performance together.

Typical Questions I get about Triathlon Nutrition

A sports nutritionist worth their salt, will deliver a tailored plan for you to achieve your sporting goals. They should identify your goals & make a roadmap to get your there with the best nutrition advice.

Unfortunately not all ‘sports nutritionists’ deliver on this.

If you decide to work me, this is what you can expect:

  • You should expect an initial Zoom call where we’ll delve into your goals, what you have tried to date & what course of action might be most suitable. 


  • After this, you’ll receive a customized nutrition plan based on your individual needs including: your training schedule, body composition & nutritional preferences. This plan guides you on your nutrition, lifestyle & supplementation where applicable. 


  • Each week you will check-in with me via a designated link. Here, you will detail how your week went in terms of your nutrition and lifestyle habits.


  • You’ll then receive feedback from me within 24-48 hours via e-mail/voice message/video message/video call. Video calls are offered every 2-4 weeks depending on your personal preference.


  • Any messages sent to me after this, will be responded to in the same time-frame as above (i.e. 24-48 hours).

You will have a check-in day – once per week. Feedback will be given to you within 24-48 hours. Any e-mails after that will be responded to within 24-48 hours.

This is dependent on what suits you best. Feedback is generally sent via e-mail or voice message but video messaging is also another option.

Zoom calls are also offered to the client every 2-4 weeks. The frequency of these calls is also dependent on your own preferences.

How long is a piece of string?! This is dependent on the client & their individual goals. 

Example 1: Some results can start to occur within the first few days. For example, digestive issues that had been hampering a triathlete’s performance can potentially be cleared up straight away – by making some changes to their diet and thus improving their performance. 

Example 2: If an athlete is looking to lose some weight for a specific race or event & their current weight is off this target – the timeline can vary. This could be anywhere from a few weeks to more than a year depending on how far they have to go.

In general, since the focus is on education & empowering the athlete through sustainable nutrition and lifestyle changes; I encourage a minimum of 12 weeks commitment. This is the length of time recommended to embed these habits into your life.

If you’re looking to maximize your performance in your Triathlon race and gain the edge on your opponents.. then having the nutritional & lifestyle tools at hand is vital.

Whether that’s having the energy to out-swim, out-cycle or out-run your opponent or shaving off time off your own PB in a race – all these come back to your nutrition.

Prices in the Republic of Ireland for a once-off consultation with a sports nutritionist can range anywhere from €80-€200/hour depending on your location.

Considering you’re likely to be seeing your nutritionist weekly, the cost becomes unsustainable after a short period of time. That’s why I offer coaching where it is €149 every 4 weeks, which works out at €37.25 per consultation! #ValueForMoney
