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