I've been frustrated with my 910XT: first one filled up with water and died at Southbeach tri in Miami, and now the second one turns off when I try to follow courses. But, the $399 was worth the scientific proof that I finished the 2012 IMSG swim leg!
http://connect.garmin.com/activity/175826129 I had the autolap set on 500 yds...check out the splits: 5:46, 5:59, 6:06 (looking like a 52 minute swim!), 8:18 (hey, why are the boats creating so much wake), 9:51 (wow, where'd the storm come from?), 10:10 (Lt. Dan in Forrest Gump: "Is that all you got!?!?), ...
I decided before I even left the park on the bike that this was no longer a race, but survival...I was not going to DNF. I'm in awe of all those that not just finished but actually raced.
Slowest Iron-distance race I've ever done, but one of the proudest accomplishments. This is why races like this should continue. I don't think anyone signed up for this race thinking it was going to be easy, even with the run course change. Very disappointed that they've cancelled such a unique event in only it's 3rd year but glad that I got to participate this year.
