Sky Sports racing host Kate Tracey told she should ‘come with a health warning’ as she flashes legs in thigh-high boots

KATE TRACEY left horse-racing fans needing a pacemaker - as they pleaded for a "health warning" to go with her latest glamorous snap.

The Sky Sports presenter posed in a mini-dress and thigh-high boots to gee-up viewers for next week's Cheltenham Festival.

And each way you look at, the "absolutely sensational" broadcaster was a hit with her admirers.

The "amazing beauty" was also called a "trendsetter" for wearing TWO belts.

And ahead of racing's top four-day event, Kate's followers didn't sit on the fences with their verdict.

Admittedly, one fan could be accused of wearing blinkers - so extreme was his adoring response to her smiling picture.

He posted: "Speechless... you could wear a old boiler suit and look incredible."

Another devotee wrote: "Definitely need some kind of health warning. Can't be that hot and not cause us guys to overheat."

Sky's popular racing host is best-known for fronting their tipping show Weekend Winners.

She's also gathering pace with her number of followers on social media, as well spearheading William Hill's coverage of the Racing League.

And despite the horsey setting, there were no long faces amongst viewers of her elegant new Twitter snap.

She was the top accumulator for glowing praise such as "Jeepers Kate!! Trying to concentrate on the horses" and "stunning as always".

Other fans trotted in with compliments like "Nice boots" and "Gorgeous".

And whatever the outcome of the big races at Cheltenham, Kate is sure to remain a frontrunner online, where she boasts 21,000 followers on Instagram and 28k on Twitter.
