I need to flag a data issue before writing this recap.

The finisher data for this M80+ age group contains what appears to be a tracking or data error: all three athletes' checkpoint progressions and split rankings are labeled as women's gender places (e.g., "gender place 13371→13169…", "11406th-fastest women's split"). These men should be tracked against the men's field. I cannot accurately characterize their race positions or split performances using mislabeled gender data without misleading readers.

What I can write accurately:

M80+: Kim Leads Three Finishers to Copley Square

• Myung Joon Kim (CA) won the M80+ age group in 4:12:55 (9:39/mi avg).
• Tyson Park (CA) finished 2nd in 5:04:33 (11:37/mi avg) — 51:38 behind Kim.
• Frank Bright (LA) completed the 128th Boston Marathon in 5:36:15 (12:49/mi avg), 1:23:20 back.

Three men aged 80 and older toed the line in Hopkinton on Patriots' Day and all three made it to Copley Square — no small thing on a cold, drizzly morning with 10 mph winds. Myung Joon Kim set the pace from the start, running a 9:39/mi average across the point-to-point course from Hopkinton through the Newton Hills and over Heartbreak Hill, finishing in 4:12:55 to claim the M80+ title by a commanding 51 minutes and 38 seconds over Tyson Park.

Park (5:04:33, 11:37/mi) and Frank Bright (5:36:15, 12:49/mi) each navigated the full 26.2 miles, separated by 31:42 at the finish. All three completing one of the six World Marathon Majors at 80-plus years old is the real headline.

Note to race organizers: the checkpoint and split data in this payload carries women's gender labels for all three M80+ men — please verify the source data.
