Last night I manged to go out for my second run this week which if you look over my past few months of activity is a pretty big deal. I have decided to use these 2 runs as my marker, my - It can only get better from here - if you will.
Firstly can I just say how much Manhattan fucks with your Garmin! to get to Central Park I have to walk 2 blocks. Plenty of time you would think for your Garmin or any other GPS device to lock on to a signal, right! WRONG!!!
I was running with Chris, we both have Garmin watches. He has the more slimline 410

I have the Triathlon (obviously at some stage I had an idea that I wanted to run an IronMan…. Silly Rob) Version, the 310xt

Now you would think that other then the screen size and the waterproof housing this would be the exact same GPS components in each version….. Hahaha, NOPE!
As we were running my watch said that I was 0.1 mile behind Chris after 1 mile. Now that doesn’t seem like a lot but lets say we were training for a marathon and we went out and did an 18 mile run, separately one of us would have run 1.8 miles less then the other! Does that worry anyone else?
As the run went on Chris and I were seeing what happened with the distance each of our watches were reporting and I have to say at the end of the 3.1 miles mine had caught up
The reports…

Now considering we ran together and started and stopped our watches at the same time (mine said it had good signal at the start) It looks as though mine thought I was starting in the middle of the park rather than the loop.
Is this a fault or do you think this is the buildings causing GPS issues?
either way it’s annoying as hell when you are trying to keep track of your progress.
Any way back to my point of laying down my marker times to be improved on over the next few months.
5k - 27:48
10K - 1:00:52
Do any of you get strange results from time to time from your GPS devices? be it a phone or a watch I would like to know.
