On a foggy Saturday in 1938, a swaybacked, 12-year-old horse named Blackie swam - dog-paddled, really - completely across the choppy waters of the Golden Gate. The horse not only made aquatic history with that trip, but he soundly defeated two human challengers from the Olympic Club, and won a $1000 bet for his trainer Shorty Roberts too.

It took the horse only 23 minutes, 15 seconds to make the nearly mile-long trip, and the short film made of the adventure shows that Blackie wasn't even breathing hard as he emerged from the waters at Crissy Field.
