The Stockton to Redding (CA) marathons were held in '55 & '56. 316 miles. DU did it in one day, the other classes in 2 days. Jack Terrell ran it one year and finished 4th in AU, he won a waffle iron.
I have copies of the circulars in the computer, but can't get them to copy.

In 2006 I got to race in the Guayaquil to Vinces, Ecuador marathon. I made a wrong turn, as soon as I got to Tarita I knew I was on the wrong path as the town was absoultey deserted, every must have went to Samborandon to watch the race. I almost made it to Salitre when the engine quit due to dirt in the fuel tank. None the less I had a great time. http://www.vincesnautico.freeservers.com/gyevinces.html
