Following the cancelation of the proposed new multi day Kent ultra in 2010 I can confirm that it is going ahead this year September 16,17,18. 3 days approx 88 miles carry all your kit with you around the kent countryside. website is www.kentultrachallenge.co.uk.
I am not involved with the race organisers however I have taken part in several of their events and they are well organised and certainly a "Challenge"
Ive already signed up and the bonus is if you sign up for the ultra you get free entry into any other of their events throughout the year bargain
