Having watched that entire Ingebrigtsen family series long ago - it was pretty clear to me (as a budding psychologist) that what Gjert did with his boys ( and tried to do with Ingrid) is to be a COACH first and a father second. A father can can choose a lot of different demeanors towards his children - a coach basically has one - to cajole coerce prod encourage and berate your runners to be the very best they can possibly be. To kick their ass until they do the work that makes them tough hard strong and ustoppable. Some of the boys (Martin and Kristoffer) opted out - which says a lot about the family in that they didn't seem to penalize those boys for those choices - just a bit of disappointment on Gjert's part I think. And in the end even
Kristoffer came around to being a runner on his own terms - and still using his father's roadmap to do it. And of course some of the boys (Jakob Henrik Filip) signed up almost completely to Gjert as coach instead of Gjert as father.
In the end there is always a price to be paid for life choices - and the one the Ingebrigtsen's paid was that Gjert as a father didn't really exist much - there was only Gjert the coach. And of course attempting to deal with a girl in the same hard way that he dealt with his boys didn't work out so well.
But in the end I give Gjert mad props for what he accomplished with his kids. I don't think either Filip nor Henrik have a great deal of talent yet he created 3 world class runners out of 5 boys using techniques virtually no one else ever tried nor tested. Marius Bakken also deserves huge props for creating something a bit unorthodox that Gjert could grab onto and tweak until it produced the results they all dreamed of.
But it was always Gjert who had the most faith, stubbornness and belief in both himself and his family.
People always want to be the best, the fastest, the strongest - but then when the bill comes due (Ingrid and all her drama) they never like the costs that must be paid in the end. Nardas' success under Gjert proves that it was Gjert as coach that created the Ingebrigtsen boys from almost raw clay. Without him Jabob Filip and Henrik would be low level office drones sitting in a cubicle most days (or working at McDonald's after seeing Jakob's diet haha) instead of world famous athletes.
The boys did the work - but Gjert is the one who created all that from nothing more than brains and determination and faith in himself and his family.
It will be very interesting to see what William does.
