Not guilty! They never explained how she cheated! Did she hop on the back of a motorbike or something?
I think her husband carried her electronic chip or transmitter in one race. She also cut some short loops off another run speeding up her time...loops that others took because they were part of the course.
Specifically...
“‘BASED ON HER SPLITS, I BELIEVE SHE DID THE NORTH SECTION CORRECTLY THE FIRST TIME THROUGH, THEN ON THE NEXT TWO LAPS, SHE TURNED AROUND AT THE YURT AID STATION, CUTTING OFF ~6K FROM EACH LOOP, OR ~12K IN TOTAL. THAT WOULD BE FAIRLY CONSISTENT WITH THE PACE SHE RAN IN THE OTHER SECTIONS.”
