In the most basic Training mode, the watch proved more accurate than the GPS functionality on an iPhone using the free Adidas miCoach app. Over a distance of 6.2 miles, the app recorded a distance of just 6.08. Looking at the route afterwards, the 410 accurately showed where we had crossed the road, while miCoach reported a near-suicidal diagonal dash through a crossing.
This is the kind of detail which makes a difference to serious runners and one which the Forerunner records extremely well. This was first put to the test in Las Vegas where we took the 410 on a five mile test run as part of our reporting duties at CES, the world's largest technology trade show.
We were able to access a wealth of information during the run without being overwhelmed due to the ability to customise how the data is displayed. You can choose how statistics are displayed on up to three screens with as many as three data fields in each and during the run you can switch between the screens or set them to auto-scroll.
Each screen can have one main display area and up to two smaller ones. We found the most informative and clear setting to be time-lapsed in the bigger field, with mile-pace and distance in the smaller two, with heart rate displayed on the second screen. With up to 35 data fields you can track everything from calories burned and elevation to compass heading and GPS accuracy.
Runs are stored in the watch so you can review your data by scrolling through the History section. We particularly like the little touches Garmin thought of. For example, a run completed today will be labelled by default as “Today”, changing to “Yesterday” then through the previous days of the week before being stored with a calendar date.
