Kevin Castille crushes M40 American record in 10K at Stanford. Only five days after winning the masters division at the Carlsbad 5000 in 14:57, new M40 Kevin Castille of Kentucky went after the kiddies at the Stanford Invitational on Friday night. He took 19th. But his real goal was a qualifying time for the Eugene Olympic Trials. Mission accomplished. He clocked 28:57.88 — only 36 seconds behind winner Dathan Ritzenhein, the Olympian. The listed American record is 30:04.43 by Paul Aufdemberge in 2005. The listed WR is 28:30.88 by Finnish Olympian Martti Vainio in 1991. At Carlsbad on Sunday, Kevin told an interviewer: “I just turned 40 on March 17 and wanted to start the Masters off right.” Castille said he hoped to qualify for the Trials in the 10,000 meters. Since the B “provisional” standard is 29:00, he’s almost assured of being in the field. The A standard is 28:15. Kevin ran the 10K at the 2004 Trials but didn’t finish.
