For disappointed runners who were slated to run the 2012 ING New York City Marathon this past Sunday, a slew of other options are available to put those months of training to good use.

While the nearby Philadelphia Marathon (November 18) is sold out, the sold-out Brooklyn Marathon (November 18) is considering expansion in response to the hurricane, so stay tuned to the website for details:

Richmond Marathon

According to its website, the marathon has received a surge of entrants post-NYC Marathon cancellation. Billed as "America's Friendliest Marathon," the Richmond Marathon is in its 35th year. Entry fee: $110.

Santa Barbara International Marathon

Athens, Greece

The Athens "original" Marathon starts at the ancient Greek city of Marathon and concludes at Athens Olympic Stadium. Entry fee: €90.

Valley of Fire Marathon
November 17
Overton, Nevada

This gorgeous race takes you through red rock desert terrain of the Valley of Fire State Park, but be prepared for hills. Entry fee: $90.

More than 10,000 runners are expected to hit the streets of Florence, in what is considered one of Italy's most scenic marathons. Entry fee: €70.

This race is unique in that it starts in the late afternoon at The Mirage casino just before the sunset over Las Vegas. Entry fee: $185 (20 percent discount for New York City Marathon entrants and the race will donate 20 percent to Hurricane Sandy relief efforts).
