January has been a record-breaking month for several American track and field stars. At the Boston University multi-team meet on Jan. 16, Galen Rupp set a U.S. indoor 5000-meter record, winning the race in 13:01.26, breaking Lopez Lomong's former mark of 13:07.00. Mary Cain, 17, broke the world junior 1000-meter indoor record of 2:40.1 established by Diana Richburg of the United States in 1982. Cain finished in 2:39.25.
In Albuquerque last weekend, 18-year-old Kendell Williams scored 4,302 points in the indoor pentathlon to better her own U.S. junior record.
At last weekend's BU Terrier Invitational, Cain won the mile in 4:24.11, missing the world junior record set by Kalkidan Gezahegne by one-hundredth of a second. Cain took more than four seconds from her previous personal best of 4:28.25 and is now tied for 20th on the all-time senior indoor list. Cain already held the U.S. junior record in the mile, plus four other distances ranging from 1000 meters to 2 miles. Rupp, meanwhile won the meet's 2-mile event in 8:07.41, beating Bernard Lagat's former U.S. record of 8:09.49.
Lagat himself was in action last weekend as he prepares to defend his World Indoor 3000-meter title in March. At age 39, Lagat won the 3000 at the Glasgow International in an early-season world-leading time of 7:49.83. In other indoor highlights from last weekend, James Dasaolu of Great Britain won the Glasgow 60 meters in 6.50 seconds. At the Perche Elite meet in Rouen, Renaud Lavillenie won his fourth straight indoor competition with a first-attempt clearance at 6.04 meters (19 feet, 9¾ inches) to improve his own French record. Will Claye won the triple jump at the New Balance Games in New York in a 2014 world-leading 17.04/55-10¾. In Sweden, Mutaz Essa Barshim leaped a world-best 2.35/7-8½ to win the high jump.
Outdoors, Ethiopia's 18-year-old Tsegaye Mekonnen won the Dubai Marathon in 2:04:32, the fastest-ever junior time. Eric Ndiema of Kenya held the old mark - which is not recognized as a world record by the IAAF - of 2:06:07.
