Well, the key is to make a commitment right from the start: try very, very hard to pick the right grandparents. If you're not willing to do that, even a huge amount of commitment, effort, and self-belief--later on--probably won't erase the gap!

The "problem" in this area, I think, is that, when they go from no training to some training, most distance runners see enormous improvement in their ability. Then, when they go from some training to more training, they see even more progress. It's probably human nature to simply extrapolate that forward--but reality intervenes.
Isn't it interesting that no one (well, no one rational) suggests that any person could run under 10sec for 100m, if only he trained optimally and believed in himself? People know better. I think it's just that sprinting ability (talent) is pretty readily observable from Day One, whereas most distance running talent takes at least a *bit* of training to show itself.
But not always! When John Walker was a boy, during New Zealand's cross-country season (*highly* competitive at that place and time) he'd go to junior races on Saturdays and do no training at all the rest of the week. He always won.
When Mary Decker was 11, she and a friend saw a sign for a "cross country" race in the park. They showed up that weekend, not knowing that distance running was involved. The friend dropped out; Mary won the 3/4-mile race, against girls who'd been running in clubs for years. Talent.
To say that there's no genetic limit to running achievement is like saying that all kids, if only they were properly nurtured and educated, could have genius IQs. Proper nurturing and education may well make a child smarter than she would otherwise have been--and training will make a runner faster than she otherwise would have been--but there is an upper limit to an individual's IQ, and that limit is (largely) genetically determined.
I wish I still had one of my textbooks from physiology grad school, wherein one of the authors said that, while it might not seem "fair," a runner or cross-country skier with a VO2max of X would never win a medal in Olympic competition. And VO2max, though just one component of distance running success, absolutely has a genetic upper limit.
Sorry.
