I’m no coach and I know Eyestone has had a lot of success, but looking at Mantz’s training it just seems like he doesn’t really do a lot of long tempos. His longest MP run for Chicago was 8 miles of MP in 14 miles (I feel like this is a workout done at the beginning of a cycle not the end), and then of course he ran the 20K US champs “slightly faster than MP,” but compared to what the other pros are doing in terms of super long tempos it seems like a miss in his training.
