Interpretation
Clara (P-INV) started at 8:15 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 5 minutes head start on Clara. On foot, Clara ran 1:00:00 and Chris ran 1:00:42 — Clara was 0:42 faster than Chris. Clara took official place 12th (time-based 66th) and Chris took official place 1st (time-based 71st).
