What's happened is that so many of today's runners have grown up in a world where there's a pace they're told they're supposed to be at while walking from the chair where they put on their running shoes to the door and for every step afterward and were constantly asking questions about what their paces are supposed to be. And they were always asking about heart rates,thresholds,etc, things that Arthur never really paid attention to. His ideas are often just too different for a lot of today's runners.
Keith's book was an attempt to put Arthur's ideas into a language they could understand and I think it does that very well. But I'm not sure how Arthur would feel about the book. And I mean literally that I don't know. He might have approved. But, and I'm not sure how well I can convey this, I can see that he wouldn't be keen on it because it can set runners up to strive to run at particular paces rather than allowing themselves to, or not to. But again, I'm not certain.
Running Wizard was a way to make a specific Lydiard like program available to runners who want to use one but don't have access to a coach who is oriented that way. It's computer generated and I can't think of a way a computer could put "enjoy yourself" into a pace or distance for someone to use. I've never asked Nobby about how he thinks Arthur would have felt about a computerized version of his training. He trusted Nobby enough to will his, Arthur's, intellectual property to him but Running Wizard came along several years after he died so it was not Arthur's idea. I do know that Nobby is always available for people who bought RW if they need to make some sort of adjustment.
When my kids decided to go out for their first season of high school cross country I told them to run for 30-35 minutes each day in the month before practices began. That was all. I knew they'd they'd find a pace that was easy enough that they could do it day after day. I also knew that they had ambitions to be good and would not poke along a lot slower than was necessary.I knew this because that's how I started and how every other runner I knew did. None of us went out for our early runs after checking charts or looking to cover a mile in X number of minutes. The pace found us.
And it was enjoyable. I cannot imagine a run being really enjoyable if I'm constantly checking a watch to adjust my pace to get it "right." I often didn't even wear one. I'd check the wall clock before leaving and on coming back. Lots of us did that and I went from not being able to run a single mile at better than 6:00 pace to once managing it for a marathon. The biggest factor in doing that was doing a LOT of running and the biggest factor in doing that was that the runs were mostly enjoyable. So I always tell people I'm advising to make their runs as enjoyable as they can.
I imagine there are people who really enjoy knowing how fast they're running for every minute so maybe that's what they should do but I think that's actually can be limiting at times, it's the very kind of thing Arthur was referring to when he said the thing about runners who incorrectly think that if they run faster than 4:25/km they'll get poor results. In years of advice I got first from Arthur and later from Barry Magee I was never told to run at any kind of pace and I was never asked about what paces I was running. So if I'm in a discussion with someone wanting to use Arthur's method, Arthur's, not someone else's interpretation of it, I'm going to try to steer them clear of trying to maintain any specific pace in their training.
