I took out a personal injury policy with Combined Insurance a few years back when I was doing a lot of bike racing (Isle of Man etc). Was pretty reasonable at about £50/quarter; covered all sorts of stuff like £100 per night in hospital, various (sometimes large) payouts for injuries depending on seriousness etc, plus it had £50k of life cover. Not 100% on the figures, that's just from memory.
Absolutely no restriction on what it covered, so that includes bikes, planes, ferrets, BDSM... ahem. Caught someone breaking into my house in the middle of the night and hit them so hard I broke my scapula (shoulder bone thingy). Sure enough, paid out straight away.
Hope that's of some use...
