Most of the advice is there above. You are obviously a very good runner, so you don't need to worry about that. In fact I'd argue that to do the BGR is not about being a good runner, its more about fell experience and time climbing and descending.
because of location I never did 10k per week on the fells week in week out but did go to Lakes and Wales probably fortnightly and did at least 6 hour days and occasionally 10 hour days in prep. Also went to Peak and did things like the Kinder Dozen. Although races are fun, I think there is a danger of too much thinking that they are good prep. You work so much harder in a race for a shorter amount of time, and the big challenges are more about slower endurance, dealing with bad periods and after about half way the big issue is then psychological. Unlike marathon running where your training runs might be well over 20 miles, I doubt most people ever do more than about 25/30 in BGR or Paddy B prep. You just discover that you can actually keep going and you aim to hit key time milestones within your personal schedule. Therefore perhaps, rather than plan to race after 3 Peaks use your lakes time wisely to learn the route, get your timings right and get the ascent/descent in your legs. Combining 2 legs is an excellent way of recceing route and learning pace judgement etc.
