HRE......Of course still today there are a lot more % of world class runners at 100-140 miles than at 80-85 miles. But more and more low mileage runners will break through. F.ex Geoffrey Kirui shows that it`s no problems to reach the world class top with about 80-90 miles if you just got the talent.
About Kawauchi he shows that even if you lack the very best talent you can reach your optimal aerob strength by just running singles and relatively low mileage.
One of my kenyan runners did 13.25 / 28.20 at 5000/10000 in Eldoret,Kenya when he was age 16. He then always just ran singles in training for about 60-80 miles per week. He comes from a very talented family .
I think that Kawauchi and some others demonstrate the Law of Diminishing Returns. One of the lessons I wish college runners in the US who decide to give up serious running because they can't get into a program, need to work full time and don't think they can run doubles and 100 or more miles a week. I'd like to see a lot of them decide to do like Kawauchi, work full time, run once a day and keep on with the sport. I think we'd see a lot more depth in US running. However, a huge part of Kawauchi's running that his would be imitators rarely mention is that he races pretty much weekly.
Maybe you're onto something. You'll like this. Ron Clarke always ran twice a day but he told me he'd have been exactly the same runner on one run a day. He didn't think of his morning 5-6 miles as training. It was a date he had with his wife who rode along with him on her bike. Still, he DID run twice a day so even he is speculating when he says he'd have been as good on one run.And in Marty Liquori's book, I always forget the title, he wrote that it was "presumptuous" for runners doing 70 or fewer miles a week to run twice a day.
But until we see the once a day 80 or so mpw types winning the major races and topping Track&Field News' annual rankings, the burden of proof lies with guys like you who say you don't need all that volume. Really, if you were looking for a project a great one would be to document these examples you bring up here.
