Well Ben, what would you like to know?
It is run mostly across farmland, crosses stiles, public footpaths etc. No navigation skills needed as the route is fully (and very ably) marshalled. If it has been wet the course can be extremely muddy which just adds to the fun.
Approx. 50% of people that complete the course are walkers. There are two checkpoints that will provide you with as much cake as you want. At the finish you get a certificate and all the apple crumble you can eat.
It is very much a no-frills event, no chip timing nonsense, no goody bag, just turn up and enjoy yourself.
Er, running out of things to say, but please post back if you want to know anything else. Except to say (from someone that enters 20-30 events a year) that this is absolutely my favourite event of the year, really cannot recommend it enough. You say it is close enough to your home to merit automatic consideration - enter now because they will almost definitely reach their full capacity. I have to travel a reasonable distance, but this will be my fourth consecutive year.
Hope this is helpful.
