Interpretation
Clara (P-INV) started at 8:15 AM; Heidi (M-INV) started at 8:13 AM. That gave Heidi a 2 minutes head start on Clara. On foot, Clara ran 1:00:00 and Heidi ran 1:01:51 — Clara was 1:51 faster than Heidi. Clara took official place 12th (time-based 66th) and Heidi took official place 9th (time-based 106th).
