Don't have much meet experience. Going to the yonkers meet next weekend.
If I swim a 200 free first event, then a 50, will it ruin my 100 free if I want a PB in the 100 free? Assume 20 minutes between the 200 and 50 and 30 minutes between the 50 and 100.
Based on your 26.8 50 time, I'd work on swimming some repeat 50's trying to hold 28 - 28.5 (but add a couple seconds if you're going from a push as opposed to a dive). The goal should be to give you a good feel for your opening pace, plus build some endurance for the back half. Then try some negative split 100's, going long, smooth, and strong while holding back a little for the first 50 and building the second 50, working each turn hard from inside the flags. Maybe 32 - 33 from a push for the first 50 and try and pick it up to 31 - 32 for the second. Then put it all together and time trial 100's regularly. With 26.8 50 speed, you should be able to get under a minute fairly soon and can go on to your 55 second goal.
