How much distance should be covered underwater by the competative swimmer in First Breaststroke Swimming Dive?

off the dive, a good place to aim for is the 15 meter mark. dont worry, you wont get disqualified, since its breaststroke. dont forget to get in your powerful dolphin kick right as you end your pull, this will give you a couple extra yards|||u mean a breaststroke pullout? no shorter than 5 yards.|||the ideal would be about 4 "lines" (on the bottem of the pool, normally there are 10 lines) out.|||Well, you're only allowed so many movements before you have to go to the surface.. You dive, you can do a single dolphin kick, you do the breaststroke pull out, you do one breaststroke kick, and after that you have to surface the water and start swimming.
