Hi@Nthep:-
A class cannot be both an instance and subclass of the same class. In particular, Tour of Yorkshire is a group of events, each of which is instantiated by year, e.g., 2015, 2016, and 2017. Therefore it cannot be the case that Tour of Yorkshire be both an instance of, and a subclass of stage race.
For this reason, the correct claim should be subclass of stage race, whereas each of the three editions are instances of Tour of Yorkshire.
- Well this might have been sorted sooner if the idiotic design of this site allowed edit summaries for each edit rather than only in limited circumstances. Nthep (talk) 22:48, 27 December 2017 (UTC)
