93% of all bets in the last 24 hours have backed the 23-year-old.
Bryony Frost has had her odds slashed on winning Sports Personality of the Year, following her historic win at Cheltenham Festival.
The 23-year-old became the first female jockey to ride a top-level Grade One Cheltenham Festival winner on Frodon, and bookies have reacted accordingly.
Bookies have cut odds on Frost, from 100/1 before the Festival started, into as short as 20/1.
That’s due to a punting frenzy on Frost following her unbelievable Ryanair Chase win, with a whopping 93% of bets in the last 24 hours.
Frost is aiming to be the first female to win it since 2006 to win SPOTY and is a vocal supporter of the Injured Jockeys Fund, basing herself at the IJF’s rehabilitation centre at Oaksey House in Lambourne.
Oddschecker spokesperson George Elek: "It was Ladies Day all over again at Cheltenham on Thursday as Bryony Frost and Lizzie Kelly emerged victorious in a two of the most entertaining races of the day.
"What a fairy-tale ending for Frost and Frodon as the gutsy pair saw off stiff opposition in the Ryanair Chase, resulting in what will go down as one of the festival's iconic moments as they were so warmly welcomed to the winners' enclosure."
