Here's what I gots ta do to run any age-graded 80's (scraping the bottom of the national class barrel) in 2011...
3k ~ 9:19 I ran 9:15 in 2010 and 9:29 in 2009 in my only 3k. I'd say my only shot would be a find a track meet. Preferably one with a downhill grade all the way around. Come to think of it, I like that idea for every distance!
5k ~ 16:23 Possible if I stay consistant ~ I ran 37 seconds faster last year.
8k ~ 26:56 Gotta find the right race for this one, which is hard.
10k ~ 34:06 Again, possible. More than a minute faster last year, and 19-20 seconds off this mark last week.
12k ~ 41:10 Not too many fast 12k's out there. Maybe Bridge to Bridge in the fall.
15k ~ 51:55 Don't know of any fast 15k's. Anyone? Anyone?
10 mile ~ 55:55 Right now, the endurance ain't that good, but maybe.
Half ~ 1:14:19 See ten miler, add a 5k...and this would be a pr. I think divine intervention would be needed for this one.
Best chances are probably in the 5k-12k range, since that's primarily what I'm planning on training for.
