His dam, Star of Goshen, was a stakes-winning daughter of Lord at War, a multiple grade I winner whose victories included the 1985 Santa Anita Handicap.

[1] At a 2007 yearling auction, the as-yet-unnamed Pioneerof the Nile was bought back by Zayat for $290,000 after failing to achieve bids commensurate with the owner's expectations.

[3] As a two-year-old, Pioneerof the Nile debuted August 4, 2008, in a Maiden Special Weight (1 1/16 of a mile on turf) at Saratoga, where he finished fourth, beaten two lengths and a half.

[5] His next start came in the Grade I Breeders' Futurity Stakes at Keeneland, where he stayed in last of the eleven runners before making a bold move on the far turn.

[6] He then started as the eleventh choice (in a field of twelve) in the Breeders' Cup Juvenile, which was held at Santa Anita Park that year.

He moved up to third before the far turn and unleashed a rally and battled with I Want Revenge to win by a head in a final time of 1:41.95 for 1 1/16 miles.

"[9] Pioneerof the Nile began his three-year-old season in the Robert B. Lewis Stakes, on February 7 at Santa Anita Park.

[12] He broke well, pulled his way up to pressure the front runner, New Bay, before moving alongside him on the turn, then took the lead in the stretch and opened up to win by 1 1/4 lengths, with a final time of 1:43.35.

[13] On April 4, Pioneerof the Nile started in the Santa Anita Derby, in what was slated to be a showdown between him and Sham Stakes winner The Pamplemousse.

But with The Pamplemousse's scratch due to injury the morning of the race,[14] his main competition was El Camino Real Derby winner Chocolate Candy.

When they entered the stretch, Pioneerof the Nile took the lead, and started to pull clear, but had to withstand a late charge from Chocolate Candy.

Pioneerof the Nile battled with the rest of the field and held second by a nose over Musket Man, but was 6 3/4 lengths behind Mine That Bird.

[21] Pioneerof the Nile started next on May 16 in the Preakness Stakes, where he faced Mine That Bird again, along with impressive Kentucky Oaks winner Rachel Alexandra.
