A couple of months ago Nike made an announcement. It has put together a team of diverse leaders in all aspects of training in order to achieve the so-far humanly impossible Sub 2 hour Marathon the so-called Breaking2 .
They have targeted three runners that are capable (according to Nike) of achieving the impossible. Eliud Kipchoge of Kenya, Lelisa Desisa of Ethiopia and Zersenay Tadese of Eritrea.
On January 26th. 2017, Ed Caesar from Wired magazine traveled to Kenya and had the opportunity to train and observe Kipchoge.
One of the days he spent there went on a run with Kipchoge and his training group:
It was during this period that I reflected upon the happy fact that I was not dead. Kipchoge has run whole marathons almost twice as fast as we were moving at that moment. Why had he chosen not to crank up the pace? Why hadn’t he killed us? Kipchoge is polite to a fault. Was he simply humoring his guests? When we returned to his training camp, another possibility emerged. This was a recovery run, and Kipchoge really does take his recovery runs that slowly. The data the Nike science team analyzed from his GPS watch shows that the kind of run he had done with us was exactly the kind of run he would have done anyway.
Caesar goes on:
I knew Kipchoge was fast. I didn’t understand how slow he could be. This, I thought, might be a moment to learn something.
