Clarendon Marathon is on this year: 7 Oct 2012

After a year off, the Clarendon marathon is back.  There are still full, half and team options.  This is what the organisers say:

"If you are looking for a marathon which is off road, picturesque and challenging then running the Clarendon is the ultimate. Our route takes you from Salisbury to Winchester along the ancient Clarendon Way with a few extra turns here and there to make up a full 26.2 miles. More than 90% is off road, with the trail following country tracks and paths many of which have not changed since being travelled by the ancient Kings and Queens of England."
