Despite the weather getting a bit nippy, the brave women bared all as they posed naked on horseback for the cheeky photoshoot.

Flashing their bottoms and cracking their riding whips, the girls proved they were up for a bit of horseplay.

In one image, the group goes for a naked horse canter, wearing nothing but their helmets and boots.

And in another photo, a jockey is seen getting her horse ready for racing, dressing him in a fancy boater despite her own missing trousers and bare behind.

The calendar's cover image sees the group laughing together while crammed in a tub, clearly enjoying the light-hearted shoot.

While another cheeky picture shows the girls tapping each other's behinds with their whips as they pose in nothing but their jerseys.

The models featured are point-to-point riders - jockeys who race over fences with hunting horses.

And they proved they weren’t horsing around with their charity ambitions, after having to select just 12 glossy photos from around 1,000 images shot on three separate photoshoots for their calendar The Big Reveal.

The calendar includes snaps of point-to-point champion Gina Ellis among the riders and the photoshoot took place at Fern Farm in Adlestrop, Gloucestershire.

The girls also posed behind the greenery of Stratford Racecourse in the raunchy snaps. 

The calendar will raise money for the injured Jockeys Fund, which provides medical and financial support to riders and their families.

Organiser Leanda Tickle said: “It's a charity which is close to all of our hearts, and while we hope that we won't ever need it, one day we might. 

“We've had great fun and the girls have been awesome, we hope the calendar will be a best seller and we would like to match the amount that the boys raised last year.”
