I participated in the Komen race in Oct 2005 in Dallas, TX. My sister lives in Dallas and I went down there and ran it with her. Luckily, we were in the front and we ran it so we were ahead of the crowd. Dallas is the first location that races were ever run so it was HUGE. Over 40,000 participants so it was crazy. If you were a walker in the front or the middle, you could get plowed over by runners coming up from behind - especially children. I think the smaller races would be alot better but the sponsers at Dallas were fabulous and it was a well run

event.
Have a nice weekend
