Do you think that those factors suddenly trebled over a small number of years? And if the list in incomplete you can always go into Wikipedia and add the missing deaths to improve the data.
I don't know if they have trebled, but without that information, or some other means to understand exposure, the number of deaths is meaningless.
edited to add: and exposure also cannot account for other factors, such as how difficult the organisers make the race
As I said originally it is interesting that the death rate has tripled. It may be that the factors you cite are responsible although I cannot recollect anything that would indicate that they changed significantly over the relevant period. But it is an interesting enough observation to be worth asking more questions. Of course if helmets worked as suggested then you should have seen a big decrease in deaths following mandatory helmets, not a big increase.
