Run, Karla, Run!

Want to run one of the biggest marathons in the U.S.? You’ve got to know when to register.

Registration for the 2016 TCS New York City Marathon lottery opened on Thursday, January 21 at noon ET. (I’m one of its race announcers.) It’s the largest marathon in the world, and one of the toughest to get into.

Like the TCS New York City Marathon, America’s biggest marathons are in demand as some of the largest in the world. And most of them sell out before race day. So here’s how and when to register for the 20 biggest 26.2-milers in the U.S. Many of these races offer half-marathon, 10K, 5K, or other races distances, too.
