My favourite kit and nutrition

  • Injinji – Runners protect your toes. Avoid discomfort and minor injury. Run more. Run faster. I use them.
  • Garmin 90-degree charging adapter — The small adapter that keeps your charging cables tidy. Essential for race day. I use one.
  • Garmin charging puck — the fastest and most reliable way to top up your Garmin before a session. I use one.
  • Ravemen FR300 — Front light that mounts directly under your Garmin or Wahoo head unit. Keeps your bars clean and your beam pointed where it matters. I use one.
  • Body Glide – The blue anti-chafe stick that all swimmers and many runners use. I use it.
  • Maurten — The race nutrition trusted by elite athletes. Gels and drink mixes engineered to be easy on the stomach. I use them.
  • Garmin Varia RTL515 — A radar rear light that alerts you to vehicles approaching from behind. Pairs with your Edge or Garmin watch. I use this model.
  • Favero Assioma Pro RS2 — The power-meter pedals most serious cyclists choose. Accurate, easy to move between bikes. I use this model.
  • Garmin Forerunner 970 — A serious choice for a pro-grade triathlon watch. I use this.
  • Polar H10 — My daily driver for accurate, waking HRV readings.
  • Wahoo ELEMNT Roam 3 — The bike computer that has the feature Garmin lacks: usability. I use mine on most rides.
