In the USA I partner exclusively with Power Meter City.
Generally you get a 10% CASH discount with the code the5krunner10 when that code is used at checkout.
However this discount is not allowed to apply to most Garmin, Favero (Assioma) and STAGES purchases.
As from NOW, PowerMeterCity will INSTEAD give you a 10% store credit on Garmin, ASSIOMA & STAGES purchases that you can then use against any other product. AND you can still use my the5krunner10 discount AS WELL AS THE STORE CREDIT on the second purchase, providing it is not for a Garmin, Favero or Stages product
Why I partner With PowerMeterCity: The owner, Josh, is a great guy and keen to grow his business. Hopefully, like me, you will want to help the smaller companies with a passion for customer service. If you want anything to do with, ahem, ‘power meters’ or ‘stuff related to power meters’ then the name is on the tin. They do what the name says.
Admittedly, PMC don’t sell cities.
PowerMeterCity has a 95% EXCELLENT rating on TRUSTPILOT

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.
