1) 5K: My PR is 20:44 (Menlo-Atherton Big Bear Run 5K, May '12). Christpants, I feel so so certain I will never run that fast ever ever again.
3) Half Marathon: My current PR is 1:38:52 (Healdsburg Half, Oct. '12). That PR is so old at this point that my only real goals are to 1) run a sub-1:40 again & 2) get a shiny new PR.
4) Marathon: After 3.5 years of injuries & other setbacks, I *FINALLY* ran a new marathon PR of 3:31:45 (California International Marathon, December '16).
