I think this seems to fit the bill of what you're after! http://www.purplepatchrunning.com/index.php/26-2-team-challenge Great team event.
20 miles in a day is definitely a long run It's like extreme interval training! You will certainly get some benefit from it without having knackered your body doing 20 in one go.
From the website: "The race will be run over a new course to circumvent the flooding we encountered last year."
Congratulations on giving up, BC, and well done on discovering the benefits of doing so. Good luck and long may it continue
Never mind the controversy ...I'd like to know where I can get a pair of those socks meself
