Garmin's Forerunner 245 Music lets you track runs and stream tunes

Garmin has officially unveiled the Forerunner 245 and Forerunner 245 Music, after months of steady leaks surrounding the running watch duo.

The follow-up to the ageing Forerunner 235 first appeared in an FCC filing earlier this year, before a retail site listing posted this month revealed much of the pair's specs. Now, both the non-music and music variations of the 245 are officially available.

Naturally, the headline features include GPS, advanced training status metrics, support for Garmin Coach and the company's Pulse Ox sensor, helping the user gauge how oxygen is being absorbed.
