A key part of improving your performance and beating your PBs is understanding your base levels to begin with, so it’s wise to invest in a reliable heart rate monitor so you can start tracking your training.
Not only will they give you the obvious details (like your heart rate in real time) they’ll also measure a wider variety of analytics depending on your device. These can include your speed, power and size of your stride.
Garmin has a wide range of heart rate monitors available with each offering particular advantages and specialisms, so we’ve put together some of our favourites.
If you’re looking for an alternative device, we’ve also included some different brands below for a broad range of options for you to consider.
