Sunday: Some Saturday events are also on Sunday. TCS New York City Marathon will feature 50,000 elite marathoners, para-athletes, seasoned amateurs and determined first-timers from around the world, all of whom will test their mettle on a scenic 26.2-mile course that winds its way through the five boroughs. Along the route, runners will be cheered on by an estimated 2 million spectators, with some 130 live bands, DJs, innumerable portable stereos blasting and raucous house parties adding to the cacophony. Cheer hard for the last ones which is sometimes harder to run for that many hours. http://www.tcsnycmarathon.org/.
