System: Venetia Williams stayers on heavy ground

Mechanism and rationale

Her horses are bred and trained for deep ground and a test of stamina. Over three miles or more on heavy they won far more often than their prices implied from 2021 to 2023, then barely won at all in 2024 and 2025: it follows the yard's form, so check that first.

The rule

trainer LIKE 'Venetia Williams%' AND race_type IN ('Hurdle', 'Chase') AND going_group = 'heavy' AND distance_yards >= 5280
