Interpretation
Richard (J-INV) started at 8:10 AM; Eric (P-INV) started at 8:15 AM. That gave Richard a 5 minutes head start on Eric. On foot, Richard ran 1:10:11 and Eric ran 1:05:15 — Eric was 4:56 faster than Richard. Richard took official place 56th (time-based 332nd) and Eric took official place 57th (time-based 189th).
