<p>This sounds like a potentially interesting challenge down the road</p>
<p> </p>
<p>You get runners of similar ability, but they're restricted to a diet of their favorite fast food chain and are kept to the same training regimen (same number of miles and workouts per week.) One who knocks off the most time from the previous best wins some kind of prize.</p>
<p> </p>
<p>Of course, it's not truly scientific, but would be fun to read about anyway.</p>
