One mile is equal to 5,280 feet. Since one pedal stroke is approximately 16 feet we divide 5280/16 to get 330. That is, there are approximately 330 pedal stroked per mile. Since the ride is 3,030 miles you multiply 330 x 3030 to get 999,990 pedal strokes. Therefore the ride will take approximately 999,990 pedal strokes. This is extremely close to 1,000,000. That is, one million. One million pedal strokes certainly sounds more exciting than 999,990 so my guess is that the answer to the question includes some reference to one million.
