Matt Biggin sent a note about a Fat Ass 50k in Fordham, Nr Colchester in Essex on November 27th 2011. This overview is from the event website which you can find at the link below along with all pertinent details.
“Spend a day running on the trails around North Essex along a 50k route that offers a variety of surfaces to run on and sights to see. From quality single-track through secluded woods to coastal paths along tidal estuaries this event has it all.
The 50k distance is an excellent distance for both first-time ultrarunners and those who are more experienced. As a first-timer who has perhaps run a couple of road marathons this would be a excellent challenge. Not only would you break through the magical 26.2 mile barrier you would also be running off-road and having a very different experience from a road event. More experienced ultrarunners would find a route that provides a variety of challenges and would make an ideal training run for those with their eye on more challenging distances.
Fat Ass Running events are not races, they are more like social gatherings with some ultra-distance running thrown in. If you want to hammer off into the distance then of course you are welcome to, though you might find it a whole load more fun staying with the group, chatting and sharing the experience.”
