Here's a link to the official results of today's 5K; my bib number was 1243. For those of you who want the TL:DR (too long: didn't read):
Age group (40-44): 43/87
Gender (male, uh duh!): 321/654
So, top half for my age group and gender and top quarter overall. Of course, the walkers are helping me out a lot in my place overall.
