Pulse-racing news: we're offering you the chance to win a Garmin Forerunner of your choice.

Whether your preparing to tackle your first 10K or striving to break three hours in your next marathon, Garmin have a watch to help you achieve your running goal.

Garmin watches can tell you:

• how far and how fast you're running
• your heart rate and calories burned so you can see how hard you've been working
• where you've run so you can relive your runs through Google Earth afterwards

You can even download training plans to your Garmin, programming it to tell you when you need to run, how far and even whether you're running too fast or too slow.

And for when you just can't find the motivation to go out for a run, Garmin's Virtual Partner feature will help give you the kick you need. Virtual Partner allows you to race against a pre-set target pace or "race" against yourself over a previous run so you can see how just how far you've progressed.

Whatever your goal, and whatever your level, there is a Garmin to help you achieve it. To discover which Garmin is the right one for you, visit www.garmin.co.uk/Garmin-Fitness-Product-Selector, and then enter the competition below for the chance to win.
