Spark has a few articles in the Maintenace section which address this... and almost all of their stats come from the National Weight Loss Registry, so that would be your best bet, but if you can't find what you need on the nwcr website, you can always peek and see what Spark has.
I am a MARATHONER!!!
Tacoma City Marathon (3 May 09) - 3:49:13
... and I'm BOSTON BOUND!!!!
Capital City Marathon (16 May 10) - 3:36:52
...and instead of running Boston, I had a kid! And then 2.5 years later I had another one.
BUT, I've never stopped running or racing!
One of these days, I'll re-qualify for Boston. And tackle Goofy's Race and a Half. Maybe an ultra. Or a half Ironman...
