Firstly the ultra section has made interesting reading for me of late, I've signed up for london2brighton in May. Guess I'm really looking for guidance & confidence boosting, ive run a few 1/2m, a few 15m trail races.But nothing longer. I feel reasonably capable at running 40 miles a week, & back to back 15 milers over the weekend, I'm slowly increasing my long run 20 miles last Saturday, and keeping the weekly mileage increasing too.. Where do I really need that long run mileage to get too before the event? I keep trying to slow my pace, although constantly get home to discover it might have felt that way out on the trails, but actually I'm still doing the same time per km... Is running 5.30kms too quick?! ( I know it must be)! Many more questions on fueling, wha to carry etc.. But just appreciate the opportunity to start a dialogue with people who actually done these distances..
