Interpretation
Levi (X-DR) started at 8:49 AM; Jackson (W-DR) started at 8:48 AM. That gave Jackson a 1 minute head start on Levi. On foot, Levi ran 1:01:31 and Jackson ran 1:01:40 — Levi was 0:09 faster than Jackson. Levi took official place 547th (time-based 95th) and Jackson took official place 542nd (time-based 100th).
