Hi Paul,
Welcome to the forums!
We ride every saturday from the car park off of Bury Road - more details on the homepage
mbro35.co.uk/ (scroll down a bit).
Have to say I'm quite impressed/intimitated by your 5-weekly coed y trips - would love to live close enough to get out there that often! Epping is a different beast at the moment - there are plenty of trails, and some decent (although not big) hills - but it's pretty muddy this time of year.
New riders always welcome so come along.
