While I agree that the 10 minute moto is the way to go, and can see merit in having the same 10 minutes for over fifties we have to remember that the fitness drops off dramatically after fifty, no matter how much running or gym time is put in, it's called old age :'(. I know there's exceptions like the amazing Boagy and even old Bill Watson in WA but I reckon your average 55-65 year old rider is starting to feel it pretty well at 5 minutes. I have a number of 55-65 year old racer mates that work at their fitness but will freely admit that at 55 you're fitness takes a bit of a dive. We see it in Golden Oldies rugby, the fifty year olds are still ready to stick it to the 35 year old 'young blokes' but by 55 they're putting their hands up to be replaced much sooner or looking to step down a division. We should be finding ways of keeping the old fella's involved in the Nats, not giving them reasons not to enter.
Seeing that age groups are being re introduced, perhaps we could have the 10 minute moto system for all of the all age-capacity classes but have some sort of sliding scale for the age classes with the younger under 30 and under 40 age groups stay at 10 minutes, over 50 7 minutes and over 60 and 'Super Seniors' 5 minutes. That way all ages and all levels are catered for yet the fit and serious guys still get their 10 minute races in the all age races.....a win win for all.
