You are offered 10 million dollars to run a 4:30 mile within 1 year. Here are the stipulations. You only get 1 shot at it, barring practice of course, and you have to do a real mile and not 4 laps at your local track which could easily be shorter than a regulation track. 10 million would set you for life, but is it worth quitting your current job and investing a year of training for it? Elite milers would have no problem with a 4.5 time, but can a non elite miler accomplish this goal within a year?
