"I think the indoor mile record should fall. It's soft. It was set in 1997. In the context of times people are running now, it's a golden opportunity for the likes of Galen Rupp or someone else. I mean, El Guerrouj holds both the indoor and outdoor mile [3:43] records. If El G could do it ... of course, they're testing more now. You can read between the lines on that."http://deadspin.com/how-i-broke-the-indoor-mile-record-an-interview-with-a-1525556046
Despite my belief that EL G was doped, this whole article should be taken with a shovel full of salt.
Coghlan implies that EL G's indoor record is weak, then stating that Rupp should be able to break it. I disagree on both counts, but heh ho.
But he then implies that if EL G could do it (on drugs) then Rupp should be able. So he thinks Rupp is clean and is a better athlete than a dirty EL G?
Clean or dirty, EL G is in a different stratosphere than Rupp when it comes to Mile running.
Another problem with this article is the lack of knowledge of the interviewer, who states that a Mile run on a 200m track would be 6 or seven seconds faster than the 10 or 11 laps to the Mile Coghlan set his record on. So she (I think the interviewer is a woman?) is basically saying that Coghlan's 3:49.78 would have been 3:42/3:43 on a 200 track and even faster outdoors! Utter nonsense.
Coghlan had enough spells of good running outdoors over a long career and never came close to matching his indoor Mile best, let lane 3:42. He always put great stock on the indoor scene and he excelled at it. He knew the likes of Ovett, Coe and most of the European elite either didn't run indoors at all or simply used it as a marker for how their winter training was going, thus he cultivated his indoor reputation and prowess. Coghlan realised that he wouldn't reach the dizzy heights outdoors and thus focused on indoors. He moved up to 5000m outdoors because he knew he wasn't the best miler outdoors when everyone was competing. There is no way a supposed 3:42 miler indoors could only muster 3:50 outdoors.
