Just for your interest/comparison WP. I did 3PPP last year in 4.48ish, I did Ennerdale in something under 6.30, but could, I believe, have gone 20-30 minutes faster if not for bad 'trapped wind' going up Kirkfell and a bit after there. The difference is the hill work, I'm sure. I do a fair bit on the cross trainer at work to improve leg strength and over the last 2-3 years its made a big difference to 'racing' and training. I think I did Wasdale in 5.30 ish just for further comparison, I'd need to double check that tho'!
