USATF NE Grand Prix - Unique finishers

I was a bit surprised by the number of unique finishers at the USATF NE Grand Prix races, I was expecting a much lower number.  1266 different people did at least one GP race (most only did one race).  I'll do a bit more work on figuring out what race attracted the most who then didn't do another GP race but my guess is that was the 5k.  I'll also do some work to figure out the team affiliation of the 1266 people.  More to follow.
