HI! I just read the article on your blog on your review of the Garmin Coach feature for Half Marathon training plan. I just finished the 5k plan and there were so many times I thought I was losing my mind with operating this watch. In the end, I think it's great - but there are definitely some weird quirks. I am especially thankful that you point out that the watch might tell you that you have completed one more mile than you actually have. In fact, I think your example was eerily identical to my own experience... I thought I had ran 7 mi, but it said 8. (I figured it must be right, was a little deflated to find out that my hunch was right). Thank you so much for affirming my suspicions about the quirks. For the price I paid for the watch, I think it's great. Just takes getting used to.. granted - I did not experience the race event mysteriously disappearing, I would have been furious as well!
