The next edition of the International Association of Ultrarunners' annual World Championship of 24-Hour Running will be held May 13-14, 2010 in Brive, France.

The U.S. Men's and Women's teams for the event will be selected as follows.

(1) The top 3 American Men and top 3 American Women finishers in the 2009 U.S. National 24-Hour Run Championship (North Coast 24-Hour, Cleveland, OH, Oct. 3, 2009) will be automatically selected to the team if they achieve the following minimum distances in that race: 135 miles for Men; 120 miles for Women.

(2) All remaining team positions for both men and women (up to a total team membership of 6 men and 6 women) will be filled based on 24-hour performances on certified (or otherwise judged by AUA to be accurate in cases where certification is impractical) courses or tracks, in races which provide lap-recording to USATF and IAAF standards, in rank order, achieved between May 1, 2008 and January 1, 2010.

(3) Once team members have been notified of their selection and acceptance confirmations have been made by the athletes, public announcement of the team composition will be made as early as possible in the year 2010.
