Apple Watch gets TREADMILL Support via RUNN
The Apple Watch now gets ‘proper’ treadmill support via the NPE Runn treadmill sensor and accompanying WatchOS app – heartbeatz connect. Once paired with the sensor, you’re good to go with Apple Watch 2 or newer.
Using RUNN, the HEARTBEATZ CONNECT displays and records speed, pace, distance, incline, cadence and of course Heart Rate from the Apple Watch sensor.
What is RUNN? It’s a pretty awesome and super-accurate treadmill sensor that works on most treadmills and transmits all the key workout info direct to your Apple Watch (or Garmin). It was released in early 2020 handily helping many of us through CV19 restrictions on our running. You can find out LOTS MORE in this detailed review. There’s a short promo video below, from NPE, and some more images of the HEARTBEATZ app.

My favourite kit and nutrition
- Maurten — the race nutrition trusted by elite athletes. Gels and drink mix engineered to be easy on the stomach.
- Garmin 90-degree charging adapter — the small adapter that keeps your charging cable tidy at the stem. Essential for race day.
- Garmin charging puck — the fastest and most reliable way to top up your Garmin before a session.
- 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.
- Garmin Varia RTL515 — radar rear light that alerts you to vehicles approaching from behind. Pairs with your Edge or Garmin watch.
- Stryd — the footpod that brings running power to your Garmin. The single most useful running upgrade I have made.
- Favero Assioma Pro RS2 — the power meter pedals most serious cyclists end up choosing. Accurate, easy to move between bikes.
