I notice the data contains what appear to be errors — the finishers are listed under "NB25-29" (a named division) but their tracked standings reference "gender place" with women's split rankings, which is inconsistent with the athlete names and ages provided. I'll write the recap treating these three as the NB25-29 field and using the movement/split data as given, noting the split context as provided.

San Francisco Marathon NB25-29: Molnar Runs Clear in a Three-Way Battle

• Matthew Marquez Molnar (Los Angeles, CA) wins NB25-29 in 4:12:24 (9:38/mi), finishing 22 minutes clear of the field.
• Timothy Simon (San Jose, CA) runs a strong second in 4:34:58 (10:29/mi), climbing steadily through the race.
• Kevin Ma (San Lorenzo, CA) completes the three-finisher field in 4:53:47 (11:12/mi).
• Molnar posted the 5th-fastest split on the 6.52M–10.89M segment across the broader field — the standout moment of pace in this group.

Matthew Marquez Molnar controlled the NB25-29 race from the front, and his 4:12:24 finish at a 9:38/mi clip tells the story plainly: no one in this three-person field came close. He moved steadily through the broader race, climbing from 10th to as high as 5th before settling at 6th by the finish — and his 6.52M-to-10.89M segment ranked among the fastest in the wider field, a burst of pace that separated him decisively from his NB25-29 rivals.

Timothy Simon was the most active mover of the three. Starting further back in the broader field, he worked his way up consistently, and his 14.95M–18M segment was a standout stretch — one of the fastest splits on that leg across the wider race. He crossed in 4:34:58 (10:29/mi), a pace notably slower than Molnar's but enough to hold second in NB25-29 comfortably, finishing 22:34 behind the winner.

Kevin Ma, 29, ran the most measured race of the group. His position in the broader field stayed relatively stable throughout — hovering in the low teens — and he finished in 4:53:47 at 11:12/mi, 41:23 behind Molnar. His 24.69M-to-finish split was among the faster ones on that closing stretch in the wider field, a solid note to end on in the cool, overcast San Francisco morning.
