According to Garmin Connect I have done the following since 1st May 2012 (which is when I got my 405):
186 runs
Distance - 1,177.56 miles
Time - 185:35:12 h:m
Elevation Gain - 13,695 m
Average Speed - 6.3 mph
Average Heart Rate - 150 bpm
Burned - 128,233 calories
I started running by following the C25K programme on the 24th January 2012 and my estimated mileage from then until 30th April 2012 is 198 miles so my total mileage for the year is around 1375 which I am very happy about
