After hearing Arthur Lydiard's name mentioned on a few threads I've done a bit of research on his methods and I'm tempted to give it a go.
I've been running for about a year now and I've improved quite a bit but I'm not sure how long my aerobic conditioning phase should be.
Ideally I'd like to complete the programme by early summer and then keep myself ticking over untill next winter.
Have any of you tried the system? How did it work for you and how did you adapt it to the fells?
