Most tracks show trap bias within a moderate range -- perhaps 10 to 25% for the best draws versus 12 to 18% for the weakest. Sunderland does not play by those rules. The trap data here reveals one of the most extreme patterns on the UK circuit, and it has a very practical implication for anyone betting the track.
Trap 2 at Sunderland wins 30.9% from 55 runs -- 17 winners. Trap 4, in the same 61-race dataset, has produced just two wins from 56 runs, a win rate of 3.6%. Those two numbers, sitting next to each other in the data, represent the widest trap disparity on any track in the current dataset. The track average sits around 16.6%, so trap 2 is nearly double the average while trap 4 is a fraction of it.
Trap 3 also performs well at 24.1% from 54 runs, and trap 5 is workable at 20%. The clear pattern is that inside-to-middle draws are where winners come from at Sunderland, and the middle-outer draw at trap 4 is to be avoided with near-statistical certainty.
Why such an extreme split? Sunderland's track geometry likely creates a scenario where trap 4 runners face the worst of both worlds -- too wide to benefit from the inside rail, not wide enough to find clear running on the outside. Whatever the geometry, the outcome in the data is clear. When Sunderland races appear on today's or tonight's card, the trap number is the first thing to check before the form.
