Later this month the track and field world will descend on West Philadelphia for the world’s most famous track meet—the Penn Relays. For 111 years, the Penn Relay Carnival has provided an opportunity for athletes from around the world, and of all ages, to run in a track and field event unlike any other. In the past 10 years alone, more than 100,000 men and women have run at the Relays. They have ranged in age from 8 to 80. And they have included everyone from high school stars to some of the most celebrated Olympians in history (think Michael Johnson, Carl Lewis and others). The 112th Penn Relay Carvinal, which will feature more than 425 races, is set for April 27-29 at Franklin Field, and tickets are on sale now. The event always draws a crowd—in 2002, more than 50,000 fans packed old Franklin Field on Saturday alone—so if you want good seats, it’s best to act quick. Tickets and ticket packages range from $14 to $45. For more information, go to www.pennathletics.com. — T.H.
