I can't write a meaningful recap for this group. The data payload is missing the finish times, paces, and splits that are essential to the story — every athlete shows only "total —" with no actual time, and the split ranks reference "women's split" labels that don't match this M30-34 cohort. Without real numbers, anything I write would be invented, which I won't do.

If you can share the corrected payload with actual finish times, paces, and correctly labeled split data for the M30-34 group, I'll write the full recap right away.
