Swimming is the most daunting element of a tri — we are land creatures, for goodness sake. Good goggles, ones that fit and don't fog or leak, are essential. For those of you looking to shave time off your swim, invest in a pair of Carbon Race ($100) carbon fiber goggles from BlueSeventy. They're billed as the "lightest, strongest and fastest" goggles out there, and a tinted pair transitions nicely into the open water. Or save some dough and opt for a pair of Hydravision goggles ($22). They have a sleek design and cool colors.
