I don't want it to become a self-fulfilling prophecy but, it seems without fail that, I swim faster in the afternoon than in the morning. My 50's are faster by 1-2 seconds, my 100's by 3-4 seconds and my 200's by 6-8 seconds. I am guessing it is related to being more warmed up in the afternoon. I hardly ever do a warm up on the deck. I usually just jump into the pool and swim untill I feel good (about 500 meters) and then do a main set or two followed by a warm down. Could there be another reason?
I notice in the morning I need more warm up to get going. I find more kicking during an AM warmup helps to get the blood moving right and gets me warmed up faster. Sometimes, in the morning I start by kicking only for a good 200-300 before starting the true warmup. No, it is not your imagination. You are probably faster in the afternoon. But you should come really, really close in the morning.
