RACE DISTANCE

BEST RECENT HM TIME (mm:ss/km or h:mm:ss total)

HM FINISH TIME

h m s

> Your HM time is used as the base predictor. Chester HM split: 1:45 (slightly hot start).

ELEVATION GAIN (metres) m gain

> Big Sur: ~680m. Chester: ~110m. Flat: 0–50m. Each 100m adds ~3–4 mins to a marathon.

TEMPERATURE (°C) °C (ideal ~10–12°C)

TERRAIN

> PACING & DISCIPLINE

PACING DISCIPLINE 7

> 1 = Chester problem (went out hard, cramped HM 2). 10 = Big Sur discipline (controlled start, negative splits, fast finish).

TARGET: NEGATIVE SPLITS

> Negative splits (second half faster) are 2–4 mins faster on average than even-split strategy.

BASE MARATHON TIME (without stops)

h m

> Your clean marathon time. Chester ~3:45. Used to calculate running pace between stops.

> RACE STRATEGY

TRYING TO WIN / RACE HARD

> If yes: negative splits, no stops, straight race time used.

NUMBER OF STOPS (Belgium: ~20. Medoc: ~21)

PLANNED TIME PER STOP mins (default 2 min — late stops get +1 min as the fun compounds)

PART OF A THEMED GROUP (STAYING TOGETHER)

> Group solidarity adds ~10 mins but adds immeasurably to the experience.

> COSTUME

WEARING A COSTUME

COSTUME QUALITY / CROWD RESPONSE

> Base costume penalty: +10 mins. Excellent = crowd boost offsets some of this. Heavy/wrong = additional penalty.
