Swim distance at 0. I swim regularly with my 645 (run too). Last swim, it would not track distance at all. Timer continued to run, but distance stayed at 0. I've reset, but can't exactly run down the street to test it. Any ideas? I'd hate to jump in the pool and have it now work again. I manually entered the last swim, but it messes up my fitness tracker as it doesn't include the manually entered activities.
