On this day in 1995, Disneyland hosted the inaugural (and only) Disneyland Marathon in celebration of the park’s 40th anniversary. In all, 2,200 runners participated. The course made a double loop through Disneyland and then took to Anaheim area streets. The route had to be remeasured during the race when bicycle escorts turned left instead of right at a crucial juncture. The mistake resulted in a half-mile “shortcut” that had to be fixed in real time!
