THE RACE LEDGER

Seventy-five start lines. One direction.

Every race since 2012 on the record: from the 77th percentile to the top 6% in fourteen years, and the data showing the twelve weeks before the gun decide the day.

01 — The arc

Fourteen years of moving up through the field

Average share of the field finishing behind me, by year: 23% → 94%. Noisy year to year — but the endpoints don't lie.

Each point averages every ranked race that year. The 2021 dip is real: first season back after lockdowns, racing on a base that wasn't there. The dips stay on the chart — a ledger that only shows wins isn't a ledger.

02 — The predictor

The twelve weeks before the gun decide the day

Group all 52 ranked races by training hours in the 84 days before: quiet blocks beat 63% of the field. 120-hour blocks beat 89%.

r = −0.28 between block volume and finish percentile, n = 52 — modest, monotonic-ish, and honest: fitness also decides which races get entered. But it's the same dose-response the lake found in resting heart rate, now showing up on results sheets. Strava can't draw this: it has the hours but not the rankings.

03 — The ledger

Every start line, on the record

TOP n% = overall field position; AK marks races where only the age-group ranking survives. Blank cells are races whose result sheets predate the internet's memory — they stay in the ledger anyway. Latest chapter, two sprint triathlons in seven days → /race-engineering/
