Yeah, I mentioned Muir wasn't fully fit in Doha. Main point RE: Muir is that for years Tseguy and Muir have been pretty much level, always within a second or so of each other. The 3:53i is a massive departure from that trend, especially as Muir's result indicates that her fitness hasn't dropped.
3:59 is 3:59? Doesn't matter if it's indoors? Nine women in history have broken 4 indoors. 111 women have broken 4 outdoors. Yes, more people run outdoors than indoors, but that's still more than an 11x the number of sub 4 times. That's a fun crossover from our good convo about Purrier, but I think you might be getting carried away both on how comparable indoor to outdoor is, and on Purrier still. She ran 4:16 - equivalent to 3:57, sitting in the slipstream of the others until the last 200. Muir ran an entire 1500m in no man's land with Tseguy blazing ahead after she opened in 58/59 and no one else behind her. Those are two very different races. Put 2021 Muir v 2020 Purrier and I'm still taking Muir 4 races out of 5.
So Monaco, Hassan runs a 4:12 which is approx a 3:53-3:54 1500m. Tseguy can't handle it and blows up with a 68 last quarter. Doha, Hassan runs a 3:51 - even faster, and Tseguy not only doesn't blow up, but in fact holds on for a 3:54? They were basically identical races but with two drastically different outcomes. RE: Zurich, yeah Tseguy does not often do well tactically, but tactics weren't her problem in Zurich. -She didn't miss a move or fall asleep. She ran that race perfect tactically, reacting to everything Dibaba and Hassan threw down: she responded to Dibaba's initial surges, and was right there responding to the last lap surge. Just when push came to shove in the last 250m she didn't have anything left. She wasn't fit enough.
Someone screwing up tactics and losing would be Houlihan in the DL final 2018 - left too much ground to be covered in the last lap, probably could have run if she covered moves better. Zurich wasn't that.
"Impressive" -?! Dude, Tseguy popped **Genzebe Dibaba's** world record by 2 seconds. Solo. With nightmarish pacing. Houlihan and Schweizer ran a nice little perfectly controlled time trial. They get a cookie, it was nice. I like them, but in their dreams was that performance at Jesuit in the same stratosphere as what Tseguy did in Lievin. That wasn't even a top 10 all time mark by Houlihan. I really would go nuts if they ever did achieve something like that, but realistically they never will. No way in hell Shelby ever runs 3:48 solo outdoors or 3:51 solo indoors. Maybe, maybe she might squeek a WR with a Jerry Schumacher Special time trial conditions.
I like you, I enjoy our conversations as they're so pure track, but boy you're understated sometimes. Waiting for you to describe Rudisha's WR as just "a strong performance" next.
Anyway, to re-emphasize, I'm not saying she's glowing, I'm saying for an already top tier athlete to suddenly go to another level, that's got to be indicative of a pretty fundamental shift in training approaches *or* something else. 22 to 24? Yea... to an extent. I think that development matters less with phenoms who were already unreal aged 17-19. E.g. Jakob Ingebrigtsen, he ran 3:28 at 19, while say Matt Centrowitz ran 3:44 at 19. Centro cut 14s off his PR by the time he was 26, yet with Jakob he realistically has only a couple more seconds to find max until he hits his ceiling. Similarly, Klosterhalfen ran 3:58 at 20 while Houlihan did a 4:13. When you're a prodigy you're progressions hit different.
Anyway, good chats.
