Everything I have read (and correct me if I am wrong ladies - I have been known to misinterpret) is swim for power w/ your arms and your core and kick enough to keep your legs up so you have them left for later. If you are wearing a wet suit you will barely have to kick.
I would agree.
The swim should be completed as if you are doing a long distance swim. A good stroke will propel you through the water efficiently with a very minimal kick. Whereas, if you are sprinting, you typically have a strong kick and quicker turnover of your arms- probably only appropriate if you are in a pool and only doing 50 yards... and that won't happen in a tri.
I typically do not kick that much in a race. I only use it when I have to power through waves or keep someone off my heels. Otherwise, not so much.
I just focus on my stroke and gliding through the water.
