September 8, 2004 AMERICAN NATIONAL TEAM AT 100K WORLD CUP THIS WEEKEND  The 100Kilometer World Cup, the longest official World Title event in Track & Field, will be held Saturday, Sept. 11, on a flat, 10-kilometer road loop course around the town of Winschoten, The Netherlands. The American National Team at the event will be led by Howard Nippert of Blacksburg, Virginia and Nikki Kimball of Livingston, Montana. Nippert has been the leading American at the 100K distance for the past three years and is hoping for a top-10 finish in the event. Kimball has emerged as the top all-around American ultra woman the past two years. She finished 8th to lead the American women at last year's World 100K in Taiwan. The American Men's team is rounded out by this year's National 100K champion, Tim Clement of Solon, Ohio, and by Charles Hubbard of Bloomington, Minnesota. Joining Kimball on the distaff team will be this year's National 100K gold and silver medalists, Anne Riddle of Asheville, North Carolina and Ann Heaslett of Madison, Wisconsin, as well as last year's National 100 Mile champion, Connie Gardner of Medina, Ohio. Strong pack running by the quartet could put the American women among the top three national teams this year. This year's National Team is sponsored by the American Ultrarunning Association, and breaking news from the event can be followed at www.americanultra.org
