Katie takes part in the Silverstone half marathon to raise money for the charity Vision, before reprising her Freddie Mercury impersonation in the final of Let's Dance for Comic Relief.
We can't wait to see how long it took for Katie's make-up artist to apply that monster moustache.
Later on, during a weekend away with her friends, Katie takes on a number of outdoor pursuits, including clay pigeon shooting and 'Go Ape', as well as trying her hand at bowling and simulated sky diving. It's gripping stuff.
And if that's not enough, we get an extra special sneak peek inside Pricey Towers when Katie hosts a dinner party for TV journalists, to promote her new show. Look out for our managing editor, Joanna Montgomery who was lucky enough to be invited.
