I am interested in Healthing Intelligent Training if it is truely a lydiard student
I was off in the time frame a little. Livingstone grew up in Lydiard's neighborhood and did meet him, but actually trained under Barry Magee for about 5 yrs starting at age 17, so he was a bit younger than the prime Lydiard training years there. Many of his examples remind me of Nobby's explanations, and I think the book as been adapted as a text for Lydiard Foundation training. There's some interesting stories about what the general principles were and what was actually done in terms of adapting to terrain.
One nice feature about it is that it is readily available (at least when it's in stock).
