I thought we might have had both siblings caught in lies but below are Kara's race times. Some results are under Kara K. Sharp or Kara kelly-Sharp. I do not know how she qualified for Boston in 2000. She would need a 3:40:59 based on the old Boston Qualifying standards.

NYC 1998 - Kara ran a 3:58:39

I also stumbled upon Kevin's Boston Qualifyer race, I honestly believed that it did not exist. I do not know if it is legit since it was so long ago. The timing mats only recorded the start, half and finish. I did check and it was like that for most runners in 1999.
Chicago 1999 - 3:08:35
Boston 2000 - 3:31:00
Boston 2001 - 3:45:05
