This morning, I had instances where I had to slow down behind slow swimmer, forced to change from free to breaststroke. My Garmin Forerunner 735XT detected the change in stroke and has recorded two 25m lengths rather than 1! Thus throwing out total distance and other stats.
Hey that worked. Thanks. Don't see why Garmin can't provide that functionality. I used to use a Swimpool Mate and even with that cheaper watch you could changes stroke etc....
