Last month Running Bug ran a competition to review and keep a TomTom Cardio Runner. I entered and thought nothing of it until a few weeks later when I got an email confirming I had won one to trial, how exciting.
When my watch arrived I was like a kid at Christmas as I tore open the packaging to be greeted by my new TomTom Cardio Runner in all it shiney glory.
I had done some research into the watch but could not get my head around how it could monitor heart rate using light. I was baffled by the technology and was thrilled to be able to try it. I had read the DC Rainmaker review of the watch in an attempt to better understand the pros and cons of the watch.
I couldn't wait to get home to try out the watch for myself to see if it worked as accurately as what I have become used to when using a chest strap.
In the interests of science I decided to go for a run wearing two watches so I could compare the HR's between what I (and most other people) have become accustomed to and the new tech in the TomTom Runner Cardio.
On that first run the maximum difference I noticed between the recorded heart rates between the two units was 3bpm. I would love to be able to show you the data to back this up but had a technical malfunction and can't upload the data from this first run off my new watch.
As you can see in the above photo the difference in 1bpm. I was amazed that the difference was so little.
Since that first run however I have been able to upload the data from the watch to Strava and other fitness tracking services.
I haven't been for anymore runs wearing both watches. It just feels weird running with two watches. The plan is to complete another run wearing two watches so I can categorically state that the new technology is as accurate as the traditional technology.
Since that first run I have found myself reaching for the TomTom to log my runs. It is oddly liberating being able to run without a chest strap. The weight of the TomTom Cardio Runner is also less than I have become accustomed to, which is a nice bonus
I love the fact that you can set HR zones to run to and it lets you know if you are training in the right zone. I find this really helpful and motivational as it is constantly there to remind you if you are working too hard or not hard enough.
I am looking forward to working with the other features of the TomTom Runner Cardio over the coming weeks to see what other niceties I can find in there.
I am not going to lie, I was sceptical about the tech but form my first couple of weeks with the watch, I am mightily impressed by it.
Thanks for reading,
