12hour enduro – with teams of 4/solo/pairs. I find these the most enjoyable, as you really can go 'all out' on your laps knowing you'll soon recover for the next.
Course time ideally around 40 – 50minutes, starting with as long a climb as possible so everyone is wittled down on the first lap. Hard to describe what kind of course I'd want as they all differ significantly, but this years course at 24-12 in Plymouth was amongst the best I've ever raced on.
No running at the start, I don't train to run, I train to race a bike! So a start loop to avoid traffic would be good.
Showers – If an enduro event didn't have showers, it's unlikely I'd do it. Travelling hundreds of miles and then racing, it would be cruel not to have these on site, entry fee's more than cover the cost of having event showers anyway.
Midday start – Midnight finish.
Can I ask, is this country park you speak of in Derbyshire? Heard rumours a while back thats all.
