He will run Berlin this fall and attempt to lower his world record.
Except for the Olympics the rest rest of his races depend on if he lowers his world record imo.
If the factors are good and he is unable to break his world record than I see him starting to run Boston, NY, and Tokyo.
If he does break the world record than I see him running London and Berlin until he can’t.
I really believe he will take one more shot at lowering his own world record. If weather is bad or he will be unable to do it, then that's how it was meant to be. (you can only focus on what you can control)
In 2020 the focus will be on the Olympics and in 2021 unfortunately i think it will be too late for a world record attempt but the right time to focus on the other wmm races.
