Track Day Insurance

[carpov]

Apologies for raising yet another insurance question, but I can't find any thread which relates specifically to this.
I'm thinking of doing one of the Ferrari organised track days. I already have insurance, which doesn't cover track days and they won't extend the cover to include it.
So, does anyone have a recommendation of specialist cover?

Thanks!

Thanks both.
Looks like I've found one of the limitations of Admiral. After about 2 weeks!
