Ali - you should be keeping a very easy pace on long runs anyway, unless its a p and d or progressive run later in the campaign. I call my long run pace arm chair pace, just bimbling along. After few weeks your bodh will adapt and you will be finding it easier and able to go further. On the sub3 thread we are looking for the long runs to become shelling pea comfortable, it doesnt take long, you can then get bit progressive later in tbe campaign. Another double digit run midweek would help a bit too.
