I can't find any.
Rupp quit Boston 2018. Rupp quit Chicago 2019. Rupp has been a DNS so many times it is crazy.
I know that Geb and Bekele have had their issues, but in terms of a direct count and also a percentage of their entries, Rupp seems to be the most quitting elite athlete in the event.
He was already the most quitting athlete on the track, so when it comes to quitting he is dominant on all surfaces!
