The glamour model has struggled to be accepted in equestrian circles having recently been told that she wasn't the "sort of person" they wanted at an international polo event.
Price features in a celebrity section of the , where she tells the story of how she got involved with horses, her funniest moment on a horse and her equestrian heroes.
Hoof is run by the British Equestrian Federation and aims to encourage people to try riding by making it more accessible and affordable and by raising awareness of horse sports in general.
The new site features detailed information on how to start or return to horse riding in London, with details of which riding schools are available in each area.
More celebrities will be added to the site soon to share their equestrian experiences.
Earlier this year the federation's Legacy for London Advisory Group, led by Barbara Cassani, former chair of London's bid to host the 2012 Games, and BEF consultant Tim Hadaway, set out key recommendations for how the 2012 Games might be used to increase facilities and opportunities for equestrian sports across London.
Cassani said: "Today's launch to the equestrian world of the Hoof website is the first step in a series of initiatives we will be embarking upon with Hoof.
"We will soon announce a trial schools initiative to attract more children into riding early in their lives, making it affordable through local riding schools."
