Garmin Forerunner 305

We are an authorised Garmin dealer. All our Garmin units carry a full UK warranty (no "newly overhauled" or grey market products, unlike some sites).

All the features of the Forerunner 205 but with full heart rate functionality. The Forerunner 305 includes a high sensitivity GPS receiver and a new courses feature for optimal performance.

The courses feature lets you compete against previous workouts: you can compare your pace over your entire workout to your past performance over the same run. You can also use Forerunner 305 to train for your next duathlon or triathlon with multi-sport workouts, a feature that lets you seamlessly transition between sports without resetting the unit, so you can use it for running, biking and more.

You can customise any of Forerunner 305's main data screens — up to twelve different data fields give you instant feedback on your workout. And, as with every Forerunner, each workout is stored in memory so you can review and analyse the data and see how you've improved over time.
