M80+ at CIM: Kasamatsu Stands Alone

• Sole finisher, full distance: Takuji Kasamatsu, 82, crossed the line in 5:32:35 — the only M80+ finisher at the 2021 California International Marathon.
• Steady progression through the men's field: Kasamatsu moved from 4,403rd among men at the first checkpoint to 4,234th at the last, picking off nearly 170 runners over the final stages.
• Finishing kick: His strongest relative surge came late — his 40K-to-finish split was his most competitive stretch of the race.

There is only one story to tell in the M80+ age group at the 2021 California International Marathon, and it belongs entirely to Takuji Kasamatsu of Pasadena, California. At 82 years old, he toed the line, ran every mile, and finished — full stop. His time of 5:32:35, at a 12:41-per-mile average, is the definitive M80+ result of the day because it is the only one.

What makes the number meaningful is how he got there. Kasamatsu didn't fade as the miles accumulated — he advanced. From his position among the men's field at the opening checkpoint, he steadily climbed: 4,403rd, then 4,392nd, 4,361st, 4,312th, 4,254th, and finally 4,234th at the last timing mat before the finish. That's a net gain of 169 places in the men's field across the second half of the race, a quiet testament to pacing discipline on a cool Sacramento morning.

The final push from 40K to the finish line was his strongest relative segment of the day. Whether the field around him faded or he simply held form, the result was the same — he was moving better at the end than the beginning.

Running 26.2 miles at 82 is not a footnote. It is the headline.
