If others are training like the Ingebrigtsens then we should expect to see them enjoy similar success, because the Ingebrigtsens' success is being attributed to their training methods. But we aren't seeing others succeeding by the same methods. That suggests the Ingebrigtsens have something else going on. I bet they do.
Talent aint an attribute at all in your book? Jakob Ingebrigtsen ran the 8.2 km long Siddisløpet in 29.56 when he was 11 years old, before he started to train with his older brothers. Helped by blood doping maybe?
Talent wasn't the point, it is the supposed superiority of modern training, as shown by the Ingebrigtsens' training, as you see below.
"The truth is that when it comes to running we haven't learned that much in 40 years, because the principles of training remain much the same. It isn't rocket science - but hard work".[/quote]
"This is incorrect.
Look at the Ingebrigtsens' training and tell me who was training like that 40 years ago".[/quote]
If it is talent that makes the difference between athletes 40 years ago and today then it isnt training after all.
