I am not sure I understand what are you saying to be honest. Can you explain please?
Meanwhile, I've done my first half marathon. It was amazing all the way through. Lots of people, everybody's positive and look forward crossing finish line, new records, whatever else people run for. The feeling after you've done was fantastic.
Anyway..
Garmin..
said
that I've done 21.08 km at the finish line. I pushed the button spot on the gate on both ends. In real life I have serious reason to believe I ran 21.2 km, which is stated on the official site of the HMrt. Therefore math suggests that would be 120m off on 21.2 km, which I find quit impressive. That would be 0.56% off. Brilliant.
I did battery test as well, it was fully charged, when i took it with me at 9:00 AM, we started to run at 11:00AM (when i switched gps on), at the finish line at 1:00PM it still had 84% of charge left. get in..
By the way my miss's iphone 4s showed that we did 23.89km, which is a bit less then 10% off. It's not always that bad though. The funny thing is that it always adds distance whereas garmin tends to take a bit off, she always have better results if we run together (virtually).
