Thanks Brotherton, I am in this kind of shape - My longest road run so far was 13 mile, in about 122. I raced a ten miler 3 weeks ago and did 5815. The longest time spent on my feet so far has been 1hr 35mins, in a fell race I did at the weekend. I did mile intervals last night and knocked out 6 at 530-40 pace, off 90sec recovery. I have a 20 mile road run pencilled in for sunday, and a 10k on good friday, where I imagine I will run 34:30-35:00. The marathon I am running is on 23rd may, so I am going to do 3 long runs in April and then the Keswick Half on May3rd, then taking it easy ish. Does this sound like a decent plan of action 2 u? Thanks for any advice
