Dallas-based US Road Sports and Entertainment Group is proud to launch 13.1 Marathon® (or 13.1® as we like to call it), a series of races that will give runners and walkers a chance to participate in a stand-alone 13.1® mile race in some of the most popular running communities nationwide. All 13.1 Marathons® are first timer friendly and perfect for marathoners in training and other experienced runners looking for a run and memorable race experience.

Fields will be limited to enable novice walkers and runners a less intimidating race experience compared to events with over 10,000 racers.  For marathoners and half-marathoners, 13.1® will offer the perfect weekend long run on a closed course fully supported with aid stations, spectators and everything a runner would want as part of a fun race experience.

MARATHON THIRTEEN.ONE® races, have been created in response to the growing demand for half marathons and support for the distance as a race for people looking for a lifetime accomplishment.  While 13.1® miles have quickly become the distance of choice for thousands of people around the world, the 13.1 Marathon® series will become the race of choice for runners of all levels . The 13.1® series currently consists of nine races for 2012 in Atlanta, Boston, Chicago, Dallas, Fort Lauderdale, Los Angeles, Miami Beach, Minneapolis and New York.

This new series joins the family of events produced by US Road Sports and Entertainment Group, which includes the ING Miami Marathon & Half Marathon®, the Publix Georgia Marathon & Half Marathon®,  the First Watch Sarasota Half Marathon & Team Relay, the Chicago Half Marathon, the Publix Escape to Miami Triathlon, New Jersey Marathon and Long Branch Half Marathon and the Run Miami running events.
