Breathing and swimming.
I have just watched the london triathlon on tv and noted that many of the elite swimmers took a breath every 2 strokes. I have been practising breathing every 3, mainly due to what i have read on this forum and what i have read. Which way is most beneficial and why? I am new to triathlons and not a particularly strong swimmer. It takes all my concentration to breath every 3 strokes. Should i persevere?
