Lol. Some medals and crap kicking around in the attic, maybe a few race programmes there too. Luckily, your disbelief doesn't impact on my own knowledge of what I've done over the years. You could search out a few Americans who would confirm what I say such as Ed Dodd from Pensaukken NJ, the organiser of the second modern 6 day race and author of a book about ultras, Don Choi from San Francisco who organised the first modern 6 day race, Jim Shapiro, author from New York who ran in my first 6 day. Maybe try Andy Milroy, the International Association of Ultrarunners statistician who was a friend back then and kept complete records of every ultra. Runners World mentioned me a few times in the mid 80's. Or, you could instead get off your arse and do something others might find too incredible to believe. No, thought not.
