Normally, truck racer Mike Ryan might be disappointed by the fact that his world record for the Pikes Peak International Hill Climb was broken over the weekend – if he wasn’t the one who broke it, that is.

Although official numbers have not yet been released, Ryan told Land Line that during the holiday weekend, he and his custom-built Freightliner finished the race in an unofficial 12 minutes and 43 seconds, three seconds faster than his previous record.

Ryan’s tractor is powered by a 1,250-horsepower Mercedes-Benz engine, and can reach speeds of more than 100 miles an hour.

The route Ryan took up the mountain, incidentally, is mainly a dirt road with 156 turns and no guard rails, according to information on the event’s Web site.
