I think Fisher is good enough to win or be a medalist. I think he could probably get into the 26:20’s, maybe faster. I also think there are others who can as well though. Fisher is a time trialist. I suspect some East Africans would run just as fast in those types of races.
all that to say, Fisher and his coaches need a specific plan for how to win and they better have been working on it for a while now, because the type of race Fisher excels in is also the type other runners do too.
Farah and to some extent Rupp, trained for YEARS to win gold-silver in London. They worked on fast reps at the end of workouts and even races. They decided they couldn’t time trial with the super studs, so they decided to specify in 50-second closing laps. Farah won this way a lot, and his competitors knew he could do it…they respected him, so they tried to grind away earlier but he was good enough to hang..but you could see him suffering way more in those long fast races.
Centro knew he couldn’t run 3:28 with the studs he beat in Rio. So he worked on a different tactic and it worked. He didn’t just think, “hmm, in the final I’ll just run 50.low and beat everyone”, he worked at it for a long time.
I just don’t see Fisher with a “different” strategy yet. Just a, “ get super fit and run as fast as possible” one. I don’t think he wins that way right now.
