For me and many others, this is decidedly the most difficult event out of the three. I did invest in one lesson and will continue to do this periodically but I also found a wealth of information online. Keep in mind that according to usa triathlon rules "Swimmers may use any stroke to propel themselves through the water and may tread water or float". For some people, yours truly included, that means doggy paddle if you must especially when navigating around the buoys. It is all legal. Ideally it is best to be able to swim using a freestyle stroke with effective breathing. Ask questions of the race promoters and anyone you know who has completed a triathlon. I have found it is a very supportive group and they really encourage others to participate.
