Rhoda made her first appearance for more than ten months when finishing unplaced in the Craven Stakes at Newmarket on 7 April.
At the next Newmarket meeting she recorded her first win for a year when she won a ten-furlong handicap race in which she defeated the 1815 Oaks winner Minuet.

In June Rhoda ran twice at Ascot.
On the opening day of the meeting she finished unplaced in an Oatlands Stakes and two days later contested her first race in heats in which she was opposed by a five-year-old horse named Garus.
Rhoda won the first heat and collected the prize of £50 when her opponent was withdrawn second.
At Chelmsford in Essex in July Rhoda was beaten by Duenna in a King's Plate and then finished fourth when carrying top weight of 130 pounds in a handicap two days later.
Rhoda's third and final success of the season came on 17 September at Leicester where she won the local Gold Cup over three and a quarter miles.

Rhoda's remaining races of 1817 took place at Newmarket in autumn beginning at the First October meeting where she finished last of the four runners behind Bobadil in a subscription race.
At the Second October meeting she was beaten in a match race over the Ditch Mile by Manfred, winner of that year's 2000 Guineas.
On 28 October at the Houghton meeting Rhoda was moved down to sprint distances and finished second to The Duke in a five furlong handicap before ending the year by running second to Pendulum in the Audley End Stakes over one and three quarter miles two days later.
