I've updated the Club Championship scores - not least because I now understand how the scoring works!
I had been under the misapprehension that 5k handicap wins, marshalling, ultras, etc were on top of the scores for your best 8 races, but that is not the case. Those only count (cumulatively per category) as a "race", if they would make it into your best 8. So, for example, if you had 6 marshalling points, those would count towards your overall score if you'd done 7 or fewer actual races, or the 6 points were better than the score for one of your 8 best actual races. The marathon ladder, and the two ParkRun ladders count as "actual races". Clear?! Good!
