3:12.00 at 1200m, so 38 flat last 300m (previous 400m, 700-1100, was 55.4).
Ryun 36.4 last 300m on dirt in a 3:38, and he was so far ahead after the backstretch that he could have jogged it in. Centro was pushed all the way home. With pacers and a fast track, there is no doubt in my mind that Ryun would have run way under 3:30 and 3:50. He was every bit as good a talent as any that have ever run the mile.
