Garmin Forerunner 210

Highlights include HotFix technology to improve GPS signal; heart-rate facility, where you can set zones determined by your personal stats; and data transfer to Mac or PC via charging clip, which you can download to Garmin’s Training Centre for analysis, or map on software like Google Earth.

So what’s different from the 110? In short, you can input the necessary work/rest info for interval sessions, the chest strap is more comfortable and you can buy a cadence-measuring foot pod for £60 if you want to take it indoors (but we’d plump for the £89 FR60 if the gym is your training theatre of choice).

So is it worth the extra £30 over the 110? As triathletes, on the interval capability alone, we’d say yes.
