No problem getting them open, but a bit of a problem further opening the package to get to the bottom. Which, in retrospect, I could have just turned the thing upside down and torn from there... Amazing, but I'm confused on the distance. GPS watch measured 13.9 mi, and I'm seeing others measured anywhere from 13.3 mi to 13.9 mi. The one thing that's consistent was the elevation gain, there was about 2,200 ft of elevation gain over the half marathon route. For a run in Washington, in November, it was a beautiful day. Definitely made the "B" goal, not sure about the "A" goal until official times are released.
2200 feet! My marathon was 650', and it's considered a hillier course, at least for the area. Congratulations on a great run. 13.9 is definitely longer than I'd expect a watch to measure. I measured 26.41 for the marathon. I have seen my watch track jump around a bit if I'm between tall buildings, and maybe yours could do the same if you were in a gorge or heavily treed area that blocks the satellite signal?
