In most pools the water circulation inlets are at one end and the outlet at the other. I find I am consistantly a tad slower going against the current. The differnce in time is so small it is not significant and I am convinced it it there.[/quote]
GRANT: Actually the difference can be significant.
I used to do LAPs in a 50m pool in Singapore and was using my triathlon watch to record and store each SPLIT Time. At the end of the SWIM, to my surprise, one side was always and consistently 2seconds faster than the other. The lifeguard confirmed the pool pump system makes water flow from one end to the other.
