tbh, I was thinking along the lines of age related classes like under 35's, over 35's and maybe a masters class for those with a pedigree. I'd also be thinking of getting away from the oldschool XC format of one long slog and perhaps having 3 x 25 minute races per class. Meaning if we had 3 classes you would then have an hour between races to recover, repair and spectate.
But like I say just want to an idea of interest at this stage. No point pushing a head if only half a dozen are interested.
