If you are a 28:20 to 29:00 min guy, why would you spend $700-$1000 to go and run at Stanford, when a 29:00 earns you $3000 at the US Road Championships in Richmond the same weekend.
Stanford you pay your entry----Richmond will comp it for you
Stanford you pay for your flight----Richmond will foot the bill.
Stanford you pay for your own room and meals----Richmond will comp it for you.
A 28:30 will not even get you into the Olympic Trials. 28:15 will only give you the privelage of getting your butt kicked at the trials.
It seems like about a difference of nearly 5 grand for no real advantage.
