I second this, good idea.

I think this could only work if you had to race against ai (their pace could be determined by the previous finishing times of opponent managers) and attempt to finish the race in the fastest possible time by using kers tactics, set-ups etc, and you were given 24hr and 1 attempt to do so.
This would be more likely to work than all the best managers competing in the same race, because everyone races at different time zones and I'm sure that with this system, no conflicts will be created
Actually I think the idea would work as Patrick suggested. Since it's a championship for a league clan, or a group of leagues, the chosen time slot for the championship races would be one of the criteria if to join this group of leagues. Unlike all the global champions league suggestions this idea doesn't have to solve the time zone problem.
