The class pick for this marathon on the basis of proven distance credentials and the strongest form average in the field. Has raced at S1 712-metre level — a grade harder than tonight — which means this is a drop in company. The best performances — P96, P89 and P67 at staying distances — are the foundation of the selection, and while the most recent outing at S1 produced only P39 it was in tougher company. Closer profile that suits the long haul, decent distance suitability score, and the model's top composite rating combine to make her the pick. Trap 3 wins 27.9% at 712 metres all grades. The declining recent form is acknowledged but at marathon trips, class at the distance tends to assert itself.
