In Sacramento guy named Zinsli has a website than not only has links to results of most of the races in California (mostly northern) and Nevada, but also has the ability to search for results by a runners name. Just enter the name, and boom, up come all of the races the person has run (since 1996), complete with date, time, distance, pace, etc.
Is there anything like this for other regions of the country, or that includes track and field?
