A New York City athlete who collapsed at the finish of Sunday’s Hy-Vee 5150 U.S. Championship race and rushed to a hospital is recovering at her parents’ home in Kansas.

Doctors so far have been unable to determine what caused Meghan Newcomer, 30, to fall ill. She was carried immediately by volunteers to a medical tent and taken by ambulance for treatment.

“I was at the doctor's office all day (Monday). I feel like a lab rat! Some of my blood work is coming back abnormal, so the doctors are trying to figure out the problem,” Newcomer said via email this morning. “I hope it's not serious.”

She was credited with 10th place in a time of 2 hours, 18 minutes and 8 seconds. The race was won by Kimberly Pancoast of Kirkland, Wash., in 2.11:28.

Newcomer, a native of Prairie Village, Kan., qualified for the national championships by winning the elite age-group division in the Washington D.C. triathlon earlier this summer.

She coordinates research and care for post-treatment cancer patients through the Survivorship Initiative at Memorial Sloan-Kettering Cancer Center in New York City. She is also the triathlon coach for the local Leukemia & Lymphoma Society Team in Training.

A 10-year triathlon veteran, she won an age-group silver medal at the 2010 ITU World Championship Grand Final in Budapest, Hungary, where she posted a time of 2:01:25 for the Olympic distance.

“Even though I didn't win any prizes, it was so much fun to be a part of Sunday's event,” Newcomer said. “I really hope I can come back next year.
