It's a strange phenomenon -- go to any pro bike race or tennis tournament, and half the spectators will be clad in cycling jersey or tennis skirts. Clearly, they haven't just completed a grueling road race or five-set match, so why the athletic gear? We'd ask the same question of people who insist on walking around in track suits. Are you about to participate in an actual track meet? Are you a member of Run-DMC? No? Then leave the nylon at home, please. You're not fooling anyone.
