Youdale competed in gymnast events and was North of England Junior Gymnastics Champion for four years. One of her first television appearances was in the 1983 Thames Television show Junior Gymnast of the Year, where she finished in fifth place with 32.70 points.
She acted with the National Youth Theatre. She studied dance at London Contemporary School for Dance and was a member of the National Youth Dance Company. She also worked at FarnhamSports Centre before getting her big television break.
Youdale’s first television appearance was in the series She-Wolf of London. She appeared on Gladiators from 1992 to 1996 – her last domestic series was series 4 in 1995. She left the show after hurting her back in a fall on an unaired show in which she fell awkwardly as she tackled a contender while competing on the pyramid – trapping nerves in her neck. She later stated:
“I was beginning to see more spinal injuries. You can damage your ankle or your knee and it will recover, but breaking your neck – that’s a different story. After my accident, I decided to quit while I could. I decided it wasn’t worth it any more. I wanted to leave while I could still walk out of the studio. I love hiking and I didn’t want that to be taken from me for the sake of someone’s entertainment.”
As a consequence of her injury, the pyramid was suspended for one series and a change in the rules was necessitated (which was later adopted for the 2008 revival of the American series).
Youdale developed her young fan base, becoming a children’s television presenter as “The Games Mistress” on the video game show series Games World, and as a presenter on the game show series’ You Bet! & Finders Keepers.

Diane Youdale, following an interview with Loaded magazine quotes that “Sky reckon they’re going to run it for three to four years so I’ve said to them why not wait until the last ever episode and then I make my comeback then?” she commented. However that will all depend on how well the show does in the ratings.
