Explain what Centro's 2:49.47 split means

Saw Graham Hood run 2.51 in a TT in the old barn (flat 200m). He was in around 3.55 indoor mile shape. I'm no v^3, but I reckon centro is in 3.51/3.52 shape at current. Of course, he might not be Molson certified.

3:38.5ish 1500

I was kind of surprised they had Centro run the 1200 instead of the 1600, especially since the 1600m leg was only 3:56 (3:57-3:58 mile pace). Apparently running 2:51 is indicative of ~4:00 mile shape, so I would guess 2:49 would indicate 3:55ish mile shape, or about 3:53 or 3:54 1600m shape.

Not sure who ran what leg really matters though given how rarely the indoor DMR is run seriously on the pro circuit. I don't see any college squad breaking it.

It would be the fastest split in Penn Relays history:

In our preview, our staffer said a 351 mile was equal to a 2:48.0. I don't know where he got that but he's got a link here:

I'll ask John Kellogg for a conversion .

I'm just going to convert to 1500. At present time, if he were to run a 1500, I'd say 3:35.5. I guess you can extrapolate this to a 3:52.5/3:53.0 mile if you want.

Not true ROJO. There was a year at Penn Relays (I think 2011) where three or four guys went 2:48 in the USA vs the World DMR.

2:51 is definitely worth sub-4. 2:54 is probably worth 4:00 or so.

Surely you cannot possibly convert a 1200m time to a 1600/mile time. 400m is a hell of a long distance. Plenty for the wheels to fall off.

You all are kidding...right? The Howard grubb age-grade calculator is about as good as any for estimating equivalent performances.

No offense to Casey, but Centro was definitely who you wanted running the 1200. Too often the first leg kinda dawdles to a 2:52-53, which means Centro would have then had to make up for that with a 3:52-53 in order to still break 9:20. That's asking a lot more for a guy to solo.

They would have still broken the record, but it is in a good spot now and will take more strategy and competition to push it down further.

It puts him in the category of sub-elite. But not bad for early season.

Assuming Centro is a 2.175 guy (meaning that doubling race distance increases his time by a factor of 2.175 for mid-distance races), 2:49.47 is equivalent to a 3:37.6 1500 and a 3:55.5 mile.

If his conversion factor is 2.2, then it's equal to 3:38.4 and 3:56.6.

I'm guessing he ran the 1200 leg to give them a big lead and clear track.

That 2:49 was while he was pushing it up front whilst others were benefiting from his pacing. Plus he was carrying a baton. I would think these two factors would put him at 2:47 if they hadn't slowed him down further.

He must be in 3:49 high shape.

Bannister ran 2:52 on a torn up dirt track in practice, before he broke 4 minutes for a mile, and the latter much more of an effort.

Therefore, Centro might break 4 minutes for a mle.

What I'd like to know is what Webb could have ran 1000/1200m in 2007 in peak form. Ventolin, care to compute this?

Since the indoor DMR is only run in the US and only at the hs and college level, all the fastest-ever 1200m splits have come from college guys, up until now.

Prior to Saturday, the fastest indoor 1200m split was, I recall, 2:52.2 by Gabe Jennings/Stanford at the NCAA Champs in 2000. He was a 3:58 miler that indoor season then won the Olympic Trials that summer in 3:35.+

Kudos to the Arkansas kid who split 2:52.0 last Friday night at the Razorback Invitational.

Another way of looking at what Centro's 2:49.47 split means: on January 17th at the UW Preview meet he won the 1k then doubled back and kicked down a fresh Cam Levins in the mile in 3:58. Now Levins runs a 3:54.

It certainly means Centro is in the best indoor shape of his life and could sniff 3:50 at Millrose.
