Bolder Boulder 10K
The Bolder Boulder 10K (the nation's second largest 10K) will be held this Memorial Day (5/30/05) at Boulder Colorado. I like how they make the race into a whole day activity. The non-professional runners start early and finish at Folsom Field Stadium. After they finish, there's a Memorial Day tribute with sky divers and military flyovers. And finally, everyone gets to watch the professional women and men run the 10K. I don't know any other races where the average runners get to watch the professionals.
Below are some basic stats from the last four years of the race. The times are based on the top 100 men and top 100 women in the Citizens Race (not the professionals). Later I plan to compare these Boulder races with other 10Ks. This race is run at a high elevation of over 5284ft. How do times at this elevation compare to times at lower elevations?

I imagine that there is some effect of finish time as the number of finisher increase (more slower people) but I wonder if you could find an association between the "number" of additional runners and the change of finishtime. Some sort of regression, I would imagine.
FYI: 5-28, Knoxville TN, Expo 5k/10k It's our third largest race (next to Race for the Cure and Buddy's Race against Cancer). Last two years has been the same winner, SAMMY NYAMONGO . Race data from 1998-2004 is on the site right now... www.ktc.org

About the finish-time/number-of-finishers, there was a good comment on the River Bank post that mentioned when field sizes grow very large, the growth tends to be on the slow runners rather than on the fast. So the overall averages would likely slow as races grow very large. Not sure how this would affect the top-100 average.
Thanks for letting me know about the Expo 5k/10k race. I like the simple text file results. It's easy for me to process. I'll see if I can run my stats programs in the next few days.
I noticed Sammy had the same exact finish time (30:33) for both 2003 and 2004. That's consistency!
