swim marker

every so often we are told to do a swim marker so see how far we can swim in 30 minutes. i was very please with myself this time around as i DRAMATICALLY IMPROVED! ;) the last couple of times i only did about 31 or 32 lengths of a 25 meter pool, this time i did 40 lengths. WOOHOO! anddddd...i still had a minute and some left, i didn't want to go another lap b/c i would be able to hear the beep of my watch, so i just ended it there.
