But in fairness, there are only 52 weekends in the year... and at least those 3 dos are all on different continents. I've quite deliberately run a London Do on the Sin Run weekend, since the people attending the London Do tend to be a different group from those that attend the Sin Run. I think it is unreasonable to say we can't have overlapping dos - quite clearly we need to because there are only 52 weekends in a year
