Have you considered becoming her manager? Lots of money to be made in running competitions.
There is a big difference between being extraordinarily fit for the general population and being a top runner. For example, this year's women's 30-34 division winner in the Hartford half marathon ran at an average speed of 5:44 per mile. (This is light years away from Nessi's current 7:30 pace.) I'd have a better chance of winning my division.
Seeing as qualifying for the USA Olympic marathon trials (female) a few years back was only a 2:50 (6:29 mile), then I'm assuming the half marathon winner was truly an elite runner (very few ladies run one mile at that pace, much less 13.1). But, put Nessi's time against the local crowd in one of the many charity 5K or 10K races and that 7:30 (actually probably would be closer to 7 minute pace adjusting for the shorter distance) would have her placing in her age group (at least based on results I see in races in the St. Louis area as I can't speak for the Hartford crowd). Still, she's fast and it's not a bad hobby to do together.
What is remarkable is not so much the time or the distance but her rate of improvement. When we started running at the local rubberized track this summer, I would lap her six to eight times in the course of an hour (comfortably). After only six months, we are now close to parity.
I'll second this comment with what I saw with Natasha, after a 17 year break from running, we entered a 5K within 6 weeks of her arriving last spring and she won her age group (30-39) easily (I thought I would pace her for the first two miles to have her avoid running too fast at the start, common beginner mistake, but she kept on giving me that look which said, why are we running so slow (if she was able to continue running on her return to Moscow, it would not have been long before she would have beat me, with more than a stick
,as I never was fast at distance races). I think her success can be contributed to a little talent along with a near perfect runners body and that is my thin tail...
