multiple listings, same race

Hi - I noticed a few races listed more than once. I dont know how common this is, but it appears true for both:

Martian half-mary on April 1 in Michigan, and

Musselman Half-iron on July 16 in New York.

The problem is just that with the (very nice) threads/links in planned races on the blogs, it makes it hard to contact other members doing those races (and figure out who else is doing them).

Thanks!!

Tom
