Spirit Of Boom x Miss Penfold
Upon Request
2026 Karaka Yearling Purchase

Horse Overview
By Spirit of Boom (AUS) — a proven sire of speed and precocious two-year-old talent — this colt possesses all the attributes trainers and owners look for in early-season performers. Spirit of Boom’s progeny consistently excel over sprint distances and thrive within Queensland’s strong juvenile racing program.
He is out of Miss Penfold, by Pierro, a mare who has already produced quality performers and hails from a powerful female family. Importantly, that line includes our own stable star Golden Boom — a standout Spirit of Boom gelding with over $1 million in earnings and multiple stakes victories, including Listed success and feature sprint placings.
Golden Boom’s durability and high-level sprint success provide a proven family blueprint for this colt — speed, toughness and the ability to perform under pressure in competitive juvenile company.
This colt is eligible for Queensland’s QTIS bonus scheme, unlocking significant additional prizemoney throughout his two- and three-year-old campaigns, particularly in Saturday metropolitan juvenile races where bonuses substantially enhance returns. He has also been entered for the Karaka Million Race Series, and with his natural precocity, profiles as the type capable of targeting those lucrative early-season features.
