A Word on Wet Suits
If the water temperature is 83 degrees or less, wetsuits are allowed. If you
are racing for an age group award, the cutoff is 78 degrees. It is
extremely unlikely the water will reach 83 degrees so you will have the
option of wearing a wet suit. Wet suits add buoyancy, help with correcting
body position, and give a sense of security. T... 阅读全帖 |
