I'm a big fan of swimming with my Garmin 910XT. I use it during all training swims, and have been using it during races. For shorter races, the time penalty is worth it for me to have the ability to analyze my results after the race.
I'm prepping for my first IM and want some feedback on the pros/cons of wearing it during the swim. The largest con would be risk of it getting kicked off, next I imagine would be the drag penalty. It's a pretty bulky watch and if swimmers shave everything to cut drag, I imagine the watch would create a significant amount of drag. Anyone done testing on this? How much time should I expect to lose? I have the quick release (which adds bulk) so it will not fit under my sleeve. The two options would be under the swim cap or on my wrist. My IM swim has 2 laps and I would enjoy being able to glace down at my 1.2 mile split for pacing purposes, which makes the swim cap a less desireable option.
