Coach Nathan Fenton
The breakthrough came at my lowest point. I was doing everything right. Logging every kilometre, hitting pace targets, the strength work—but race day told a different story. My times were flat or sliding backwards.
Then Stryd launched their power meter in 2017. Finally, a way to measure what actually matters: how hard I was training, not just how fast. Power data showed me exactly where I was gaining fitness and where I was wasting effort.
I rebuilt my training using power metrics. The improvement was immediate. That's when it clicked. If it worked for me, it could work for other runners stuck in the same plateau.
Eight years and hundreds of athletes later, I learned the real magic: knowing how to interpret and personalise power data for each individual. That's what RPC does. No cookie-cutter programs. Just systematic, data-driven coaching tailored to you.
If you're working hard but not seeing results, I've been there. And I know how to get you past it.

Three simple steps to new PBs
Test Threshold
A simple 60 minute running test with a power meter will give you your threshold power, from which your personalised training plan is created.
Train to your Power
Your training plan is created based on your threshold power, and is adjusted to your current fitness level. Follow the workouts using your compatible GPS watch.
Retest Threshold
Repeat the running test to guage your progress. Your training plan is then adjusted to your new threshold power.

Testimonials
I began working with RPC in November and knocked two PBs out in the month following. Then followed marathon and 10k PBs in April and May, and another marathon PB at the end of July. Fair to say, results were immediate.
Over a 6 month period I hit multiple PBs in every distance. I went from a 3:53 marathoner to a 3:22 marathoner - this gave me the confidence that with Nathan's guidance my BQ was possible.
Since working with Nathan, I have achieved PBs over 5km, 10km, and half and full marathons - with times I had previously thought were unachievable. I wish I had started with him sooner.
