Thanks for the advice (& @HatBeard), i'll get to re-reading the book this weekend and work out the schedule, dislike warm up (well running in general), but my calf's sure appreciate it so have been adding them in recently.
Sure I'll be back for more advice.
Definitely adding a full 2 miles to the sessions that called for a warm-up was a good way to get the miles into you legs. Don't skimp on them.
