How Coaching Works

A SIMPLE, PERSONAL COACHING PROCESS

1. UNDERSTAND THE INDIVIDUAL

Goals, History, Lifestyle Constraints

2. BUILD THE PLAN

Personalised, data-informed training in TrainingPeaks

3. SUPPORT & ADAPT

Ongoing feedback, adjustments and accountability

FLEXIBLE COACHING WHEREVER YOU ARE

Coaching is primarily delivered remotely via TrainingPeaks, allowing athletes across Oxfordshire, the UK and beyond to benefit from structured, personalised support.

 

Where logistically feasible, swim, bike and run sessions can also be arranged on a one-to-one basis or in small groups.

  • Runners training for 5K through to marathon and ultra-distance events

A SMARTER WAY TO TRAIN

TESTIMONIAL

“I can't speak highly enough of Alex and the impact he had on the outcome of my first Ironman in Austria. As a full distance novice, the volume of training was pretty daunting. However, Alex's methodical approach and calm guidance made the process manageable around a busy family life. Alex also understands that training amateur triathletes comes

with an element of needing to educate on things like race prep and planning, nutrition strategy and management of emotions. These are the areas where Alex excels and I feel are what sets him apart. Austria was easily my best triathlon experience so far, both in terms of the race and how I executed the plan and much of that was down to having Alex on board.”​
