Can’t say whether or not that’s "enough" training, only your body can know, but it certainly looks good.

Just to second Corniceman — I did two back-to-back recces of leg 4 (18 miles counting the run in from seathwaite) with mates:

The first was an experienced ultra-runner, the second was a good club runner, who’s taken part in shorter fell races and has been training hill reps for months. I got round twice fine, but both my pals had a bit of a blow-up in the region of Kirkfell.

Even though our overall training volume is comparable, I’ve ran a minimum of 13 miles/month (usually more) on fells since last Sept, which they haven’t, so my anecdotal advice would be that actually getting up into the hills trumps all other training (as far as the BGR is concerned).
