Description

No need to buy a brand-new treadmill to log your indoor run. Runn easily installs on your existing treadmill and transmits speed, incline, and cadence via ANT+ and Bluetooth so you never miss a step.

Runn is factory calibrated to be accurate to within .1mph at a 5mph treadmill pace to ensure accurate readings right out of the box. This is especially helpful for non-motorized treadmills and treadmills with worn parts that may not be reaching the speeds they did when they were new.

When used with the NPE heartbeatz Connect Apple Watch application, your Runn simultaneously gets all of your treadmill data into you watch, while also including your heart rate in the Bluetooth connection to a virtual training app. Gone are the days of needing to wear a chest strap when you use an Apple Watch with your Runn!

Links virtually any treadmill to your fitness app
Broadcasts speed, incline, and cadence to apps over Bluetooth or ANT+
Connects Apple Watch Series 2+ heart rate to a fitness app with the heartbeatz connect Apple Watch app
Rechargeable with the included micro-USB cable
Battery lasts for up to 15 hours between charging

Love it!

I bought the Runn sensor to use with a Peloton Tread+ and Garmin 265 Forerunner. Just a heads up, when adding the sensor on your watch, make sure to add as a foot pod and not a smart trainer or the general "search all". It is incredibly accurate after doing a calibration.

Not ready

When it works it's ok...but it needs constant adjustments on the treadmill, will constantly show high speeds, incorrect cadence. Not worth it in it's current state

Favorite Running Toy

Since my treadmill sensor was not accurate, I went from being unable to confidently do anything other than an easy run indoors and now I'm fully comfortable doing threshold and interval workouts with accurate paces and trusting the results.

Makes my older treadmill Zwiftable!

Easy to use and connect. Love having this new ability to get new life from my old treadmill.

My email sent to NPE Team, no answer

Dear NPE Team,

Today, I received my Runn sensor (Order #2148) and wanted to share my feedback after installing and using the device.

First, I’d like to commend the ease of installation and calibration, as the video instructions were clear and straightforward. I also appreciated how easily the sensor paired with my Garmin watch, allowing me to monitor my pace directly, which is a fantastic feature.

However, I must express some disappointment regarding the accuracy of the device. As someone using an entry-level treadmill, I was hoping the Runn sensor would compensate for its inherent inaccuracies. Unfortunately, since the calibration relies on the treadmill’s own speed data—which I suspect is highly imprecise—the results don’t meet my expectations. My perceived effort on the treadmill at a given pace feels significantly different compared to outdoor running or using a treadmill at the gym.

Moreover, I was under the impression that the dual optical sensors in the Runn would enable it to independently measure speed without relying on the treadmill’s questionable data. It’s disheartening to see such promising technology still dependent on external calibration from an unreliable source.

On another note, as a Canadian customer, the overall cost of the product turned out to be much higher than expected. While I benefited from a 15% discount, I paid $148.25 CAD (including shipping), along with an unexpected customs fee of $64.77 CAD. This added expense was frustrating, especially given my disappointment with the product’s performance.

I do appreciate the innovation and potential of the Runn sensor, but I had higher expectations for accuracy and autonomy given the technology involved. I hope my feedback can help improve future iterations of the product.

Thank you for taking the time to read my thoughts, and I would be happy to discuss this further if needed.

Best regards

Sebastien apologies on the delayed message here. I sent you a follow up email to discuss this matter further. Thank you for taking this time to write us a review. As well as the 3 stars. We do appreciate your time! As well as your purchase from us. :)
