how can a sports nutritionist help you?

services and Plans


Elevate your endurance game with the “Ready to Race” plan, a series of one-to-one nutrition coaching sessions, personalised around your competition goals and ambitions. Each session will focus on the specific areas where you need help, and every session will include a range of resources and tasks to complete - including reviewing and optimising your training diet, effective fuelling, improving recovery, choosing supplements, gut training, hydration tracking and planning, race nutrition prep, race nutrition planning, increasing your practical and scientific knowledge of sports and performance nutrition.

How Does It Work:

Over 6 x 90-minute sessions (more if required/requested) we cover all the key areas you need to enable nutrition to make a positive impact on your health, performance, training adaptation, recovery, and competition success. We cover the key areas of nutrition for performance. Many athletes come to me with specific needs, such as reducing gut distress during competition, improving race fuelling, or enhancing recovery. Therefore, as personalised plan, we can continually adapt and focus more time on the areas we feel are most important for your success.

What We Cover:

We deep dive into your current eating habits and identify areas of best practice, and those that need improvement, to optimise your diet and health. We move on to fuelling training and recovery. Once we have your diet set up, we focus on race nutrition and hydration, building up a plan for competition whilst working on some gut training protocols and hydration planning.

This plan can be taken over a period of 12 months if needed, allowing you time to work on tasks and plans to be race-ready.

Due to demand, I am only taking on clients through referrals at the moment. However, feel free to contact me on Instagram if you have any questions or would like to be added to the waitlist.
