[7] Untold sustained a minor training setback in the spring of 1986 and did not appear on the track until 7 June when she was one of fifteen fillies to contest the 208th running of the Oaks Stakes at Epsom Downs Racecourse.
Untold took the lead early in the straight and maintained her advantage until the final furlong when she was overtaken and beaten a length into second place by Midway Lady, with Maysoon and Colorspin in third and fourth.
Swinburn chose to ride her in preference to Colorspin, but again made the wrong decision, as Untold appeared unsuited by the soft ground and finished a distant third behind her stablemate and the Irish filly Fleur Royale.
Once again, Swinburn had to make a choice between the Stoute stable's runners and decided to partner Colorspin, whilst Greville Starkey took the ride on Untold.
[2] The St Leger Stakes at Doncaster Racecourse on 13 September saw Untold, ridden by Swinburn, take on seven colts in the final Classic of the British season.
She briefly struggled to obtain a clear run in the straight and despite making some progress in the closing stages she never looked likely to win, finishing third behind Moon Madness and Celestial Storm.
In October she was brought back in distance for the Champion Stakes over ten furlongs at Newmarket but failed to show her best form on rain-softened ground and finished sixth of the eleven runners behind Triptych.
In 1985 the independent Timeform organisation gave Untold a rating of 112 p (the "p" indicating that she was expected to make more than usual improvement) twelve pounds behind their best juvenile filly Femme Elite.
