Thanks for the feedback sticky, monkey and wheely.
The first speedwork comes in Wk2 (of a 15 week plan) and is:
Dist: 5mi, inc Warm; 2x1600@10:05 w/800 jogs; Cool
By week 6 it is:
Dist: 7mi, inc Warm; 3x1600@9:59 w/800 jogs; Cool
Week 14 is:
Dist: 10mi, inc Warm; 5x1600@9:47 w/800 jogs; Cool
I guess it is a case of sustaining that speed over the distances that helps. But I don't quite get how this translates into speed on the day. Is it simply that your body is used to going faster for longer? I can't quite get my head around the fact that the longest long run is 11 miles but at 11.58m/m, and how that translates to (ideally) 10 minute miles on the day.
Did you all follow the plan religiously?
