She was sired by Tapit, a gray son of Pulpit, who won the Wood Memorial Stakes and started second favorite for the 2004 Kentucky Derby.

[2] Untapable's dam Fun House was a successful racemare who won five races including the Grade II Buena Vista Handicap.

In September, Untapable was moved up in class and distance for the Grade II Pocahontas Stakes over 8+1⁄2 furlongs and finished strongly to win by half a length from tonetastic at odds of 5.8/1.

[4] On November 2, Untapable started the 11/2 fourth choice in the betting for the Breeders' Cup Juvenile Fillies at Santa Anita Park.

[5] Joseph Talamo took over the ride from Napravnik when Untapable ran in the Starlet Stakes at Hollywood Park Racetrack on December 7 when the filly finished third behind Streaming and Taste Like Candy.

I like how she was handled by Rosie, how she relaxed, and she ran big, especially off such a fast effort in the Rachel Alexandra" whilst Napravnik admitted to being "very excited about her".

Drawn wide in stall 13, the filly settled in fourth place before moving up to take the lead from My Miss Sophia on the final turn.

After being hampered in the early stages, Untapable, ridden by John Velazquez moved up to take the lead on the final turn and pulled clear to win by nine and a quarter lengths from Princess Violet.

Racing on the outside of the field, Untapable (the 7/5 favorite) made some progress approaching the straight but never threatened the wire–to–wire winner Bayern and finished fifth, beaten more than nine lengths.

[13] Untapable took on older fillies and mares for the first time in the Breeders' Cup Distaff at Santa Anita on October 31 and started 8/5 favorite.

[17] For the rest of the year Untapable ran consistently without recovering her best form and posted a string of placed efforts in major distaff races.

It was expected that she would attempt to defend her Breeders' Cup Distaff title but was scratched three days before the race after she was found to be running an abnormally high temperature.

[18] Untapable made her seasonal debut in the Azeri Stakes for the second year in succession and as in 2015 she was beaten at odds-on, going down by a neck to Call Pat.
