There is an excellent book on a 600 mile endurance
race from Wyo to Denver, Colorado in 1908. Vet checks every 50 miles. My local
library has one of 500 copies. Each copy is numbered. The author has a note at
the back that researching old endurance races is his passion. The source of all
his data is given from newspaper accounts of the time. I will get the title
later if others don't have it now. Tom Van Gelder even had it as a question on
the Big Horn 100 entry form a couple years ago. There were true horsemen riding
endurance then. The winners agreed to tie after 7 days and 600 miles to save
their horses damage and split the purse.
