utter drivel
http://racingpast.ca/john_contents.php?id=180"But it wasn’t the Mile WR that he broke first. Running an 880 in the UST&F Championships, he surprisingly broke Snell’s WR of 1:45.1 with 1:44.9. This was achieved after a 1:51 heat two hours earlier. After a 53.3 first lap, he took off on the back straight, running the last 220 in 25.5.
Then in Berkeley he attacked Michel Jazy’s Mile WR of 3:53.6. After being taken through in 57.9 and 1:55.5, Ryun had to go it alone on the back straight of lap 3 after he felt the pace slowing: “I…lengthened my stride, trying to hold a steady pace.” (Gold, p.49). He reached the bell in 2:55.3 and needed a 58.3 last lap to break the record. But the fast pace was hurting: “I was gradually tying up.” (Gold, p.49)
He passed 1,500 in 3:36.1 (2nd fastest ever) and looked really good over the last 120, covering the last lap in 56.0 for a 3:51.3. He was 6.7 seconds ahead of the next runner, Cary Weisiger. “I didn’t know it was a WR until they announced it over the loudspeaker. I was surprised,” Ryun recalled later (Milers, p.320)"
he was a kid at 19y & this was about only race in his better years, '67 being quantum leap better, that he coud actually get someone to pace him
that pacer coud only get him thru in 57.9, probably about 56.9 on '70's synthetic & he had to run at least last 600 solo & it looked like pretty damn hot in berkeley
he was probably on a '70's synthetic on this day, on temperate day with ideal pacing to bell :
~ 1'41-mid / 3'27-low
he was a quantum leap better in '67, running on a poor track, solo, jogging to bell & a 53+ finish & there is always Dusseldorf !!!
he also ran 2'46.6 for last 1200 in 3'33.1WR with some wide bend running & in 95F heat !!!
also worth noting that a 25.5 finish in a fast 800 is last 200/220y split expected in a 1'39 !!!
57.9 on dirt, probably worth 56.9 on a '70's synthetic, but that is all the pacers coud offer him
no 56+ offering on dirt for him, worth 55+ on '70s synthetic
utter drivel
he wouda hoped for more like 56+ that day from pacer without doubt
