With so many watches on the market, it can be confusing knowing what features you need and which are surplus to requirements. The main features to look for are a heart-rate monitor (HRM), which will help you to train smarter, ensuring your runs are neither too hard nor too easy. A GPS will let you keep an accurate log of your mileage; particularly useful if you are training for a longer event. Lap timers can help plan your interval training, while the ability to quickly download your data to a computer-based or online diary will help you analyse your training.
Here, coach Dave Taylor, analyses the top brands to show you how you can use wrist-mounted technology to gain race places.
