The 100 was first recorded time LCM, and the 200 was 7 secs faster than my last attempt. Obvioulsy tecnique is very important, but looking at my drop off on the 200, what do you think is going on. I was told my stroke looked good on the 200. Is my conditioning bad? Should I practice more broken 2's 3x50 mod 1x AFASP a few times thru etc? I did this for SCY Zones and went from 3:07 in January to a 2:56 by April--not a bad return IMHO. Am I just a sprinter (albeit not that a fast of a sprinter) and will I not have much more joy in reducing my longer swim times? I only get 3x a week in the pool and someone told me swimming 5-6 times would get my times down...I can't devote that much time. Lastly I just bought paddles to find the slipping point in my BR pull and was happy to find only my left hand slipped a little on the insweep and only at a high pace--but not everytime. I'm still working on not "blocking out" in the water by recovering my legs before my arms have shot into streamline. Anyone have drills for this? Peter C said to work on building up speed which I am doing. Just looking for more input and ideas. I know LCM is a hard beast compared to SCY so swimming a PB on the 50 is encouraging. Thanks Rich
