The Samsung F110 miCoach (Adidas) is about the same size as Ipod Mini, and offers a small, lightweight slider casing with robust, sturdy design.

The phone is designed to be held whilst running, and as such it has a nice grip-finish on the back, to ensure the phone is comfortable in your hand.  It also comes with velcro arm straps, allowing you to attach it to your arm should you rather that instead of holding it in your sweaty hands.

The phones features are relatively ordinary, with a standard 2 megapixel camera being the pick of the bunch.  The F110 does come with miCoach, Samsungs jogging monitor - with a pre-selected voice being able to tell you how you're doing at a touch of the button.

On top of that, the music player works in perfect unison with miCoach, and the battery life helps to make sure the phone doesn't pack up straight away - although in all honesty it's a little bit weak, with only 250 minutes standby.
