The Chester Dragon Boat Festival

Yes, the list is ranked and the ranking structure is determined by:
 The number of teams a charity has registering in this year's event, The date of team registration, with the earlier registered teams going first,

The main ranking factor will be the number of teams a charity has entering to support it. So although the list is initially organised by the date the teams register by, where a charity has two or more teams entering, those charities will immediately go above all charities entering just one team – regardless of when those teams registered. Likewise, a charity with three or more teams will go above all charities with just two teams and so on.

What is the best way to guarantee you make to top spot? Be the charity with the most teams entering!
