I am surprised I haven't found the answer to this anywhere else yet. I have a dream to reach the running level at which I have earned the right to wear a mustache like Steve Prefontaine, but I have been unable to find any published social time standards required to be eligible for this. Does anyone have the information on how fast I have to be to legally have a Steve Prefontaine mustache? For example I presume Craig Engels is qualified, but I don't imagine I'll ever approach his race times. Or perhaps the qualification standard is measured by something else other than PR's/SB's? Any info you can share would be appreciated...
