Ah, spring and the annual “Buggy” race at Carnegie Mellon University. Student teams representing fraternities, sororities, and independent organizations (including students from the university’s Tepper School of Business), build and race composite vehicles around the streets of the campus. Officially known as Sweepstakes, the event has been part of Carnegie Mellon’s annual Spring Festival since 1920.

The race itself is a relay, but instead of each of five runners passing a baton, they take turns pushing their buggy—a sleek, human-powered vehicle with a handlebar on the back for the runner to push. A driver rides inside the buggy to steer it. This year’s Sweepstakes was held on campus on April 23rd and 24th. Pictured: A student races inside a "buggy".
