I have to agree with what's been said...get to a masters program/get a coach.
I've been a decent swimmer having swam and played water polo in HS, so i was pretty ok with my time when I got back in the water after almost 20 years for tri's and settled in to being about a 32-35 min 70.3 & 1:12 IM swimmer being self-coached.
Joing masters was a whole new ball game. Almost immediately, my coach spotted a flaw in my catch and combined with the increase in yds (from about 6-8000/wk to 12-15000/wk) and a huge jump in the quality of my workouts, my times dropped to about 29 for 70.3 and 1:02 IM. When in shape, I'm right around a 5:45 (so 6:00 interval) on 400scy repeats (unfortunately, I'm not a sprinter, my pace doesn't get much better as the distance shortens).
