Gasping in the turn...

Hehe ok Yeah I'm gasping in my turns on ***. and in a 200Y event there's 7 of them. I am sure I am losing seconds in my push off and glide b/c of conditioning. I am going to get into the reace prep work again tomorrow...Warm up then 1 x 200 (my mentality set) 7 x 100 on 4:00 (working my way to 10 reps) 4 x 50 on 2:00 4 x 25 on 1:00 I am curious if anyone thinks after the above workout, I should do 10 reps of say swimming 2 or 3 strokes to the turn and pushing off and repeating without rest or something like that. Is that a good way of building some stamina for that particular part of the race or am I doing enough? I read somewhere about vertical pushoff in 7ft water but my pool goes from 6ft to the dive pit. Whatever happens I can only race with whatever I have in 3 weeks.
