I wrote Kenny Moore to ask him if the 30/40 numbers put up here about Prefontaine were legend or evidence of Dellinger genius. The Olympic marathoner, Oregon Duck, Bowerman biographer, and scribe of our sport without equal responded:
Dear John,
The 26 laps of 30-40's for Pre is legend, but the 30-40 workout itself is something Bowerman had us do, so Dellinger's refinement and greater emphasis on it was not genius so much as exploration. It grew out of Bowerman being fascinated in the 1950's with Parlauf relays, where teams of two guys alternate 220's and after you hand off, (in the middle of the stretch) you have to jog across the infield and be ready to run again while your partner makes it around the curve. Bill would see how many of those 220's with (30 to 33s sec. recovery) we could do. Of course it was always more complicated than that. He loved to pair a distance guy and a half miler, such as me and Archie San Romani, to keep Archie from going 26's at first, and to prove to me that fast guys could be overcome by slower running and faster recovery.
Then, when one of Pre's many gifts was the ability to surge and recover in racing, Dellinger strengthened that strength even more with the 30-40 workouts. So we're all together here, as usual, standing on the broad shoulders of those who have gone before.
Cheers,
Kenny
I asked his permission to post this here and about his new book. He responded:
And of course you may post the 30-40 stuff on LetsRun. And tell the world I plan to show up at the Rodale booth at the Boston Marathon and keep signing books as long as this old marathoner can avoid the shakes. Maybe longer.
Best,
Kenny
