I thought that you were just unhappy that a runner is clearly faster than Tuohy. But you have now shown that you truly believe elite runners can run a faster time in practice than in a race. Most runners can't come close in practice even with the best pacers. Very few can get in the neighborhood. But none can run faster. None.
4 minute milers run 8x400 at race pace for a reason, because if they bump up to 800, they are almost cooked after a 1:59 in practice. If they try for 1200, they run 3:01. If they try for a mile, it can be an ugly 59-60-63-65. If a 4 minute miler was capable of sub 4 in practice, we would have them do it followed by 8x200 in 29 and they would have more confidence than you can imagine. You know why? If somebody runs 3:59 in practice, they will run 3:55 in a race. If somebody runs 9:39 in practice and they have perfect pacers forming a wedge, they are ready for 9:30 in a race. Any good runner or coach will agree.
