It appears a serial cheater who was disqualified from this year’s AppleTree Half Marathon in Vancouver is under suspicion again.

Emily Clark’s latest suspicious result came at Sunday’s Chicago Marathon, a race she recently admitted to course-cutting in 2013.

Clark, a 28-year-old Portland resident, crossed the Chicago Marathon finish line in 3 hours, 59 minutes, 8 seconds.

But Clark’s recorded time splits and pace bring into question whether she actually ran all 26.2 miles.

Her pace between the half-marathon mark and 25 kilometers was 12:16 per mile. But from 25K to 30K, she clocked 6:13 per mile. That’s a pace maintained by only the top 50 females in the 33,000-strong field at Chicago, the nation’s second-largest marathon.
