Ladies and gentlemen, let me paint a picture for you. The year is 1983 and you are a super fit, well geared, and highly trained ultra-marathon runner. You are getting ready for a 544 mile race from Sydney to Melbourne, Australia. You are mulling about with your peers, rubbing elbows with everybody who you know is at least as prepared as you are. You see an array of high end athletic brands on display. It is a stereotypical marathon.
