How Fast Should A Half Marathon Be Run ?

It's still 8 weeks until the Blackmore's Sydney Half Marathon but I've been reading about how fast I should run during long training runs and the race......the consensus seems to be just below the lactate or anaerobic other words

1. Just 2-3% slower than before you lose the ability to talk
2. It feels 'comfortably hard'
3. Breathing is more laboured but your not out of breath
4. 5% slower than the 10km speed

In addition the advice seems to be to stick to negative splits which would mean starting out at a little slower than this and finishing the last 2kms a little faster......

Is this what others think ?
