The point of this thread was not necessarily to bash anyone (although it does seem like we have gotten to a point where a 2:14 is a decent show, ie Tinman recent video); rather, it is a serious question of how we can become complacent with these results EVEN while our 800-5k athletes are true world beaters.
Consider the top of you milers: cole hocker, Yared Nuguse, Hobbs Kessler, cooper teare, and then dozens of guys not far behind who’d be the next American phenom only a decade ago, as we now routinely churn out 4-flat high schoolers. With this being the case, I don’t think you can say it’s a talent problem. We have the talent; that talent just can not seem to translate to the marathon distance.
On top of this, I also think it’s important to remember that we are in the age of time of super shoes giving marathon runners a friendly couple of minutes benefit to their finish times. Let’s call it 3 minutes. Now, imagine if the legends of the 70s had those shoes. Do you really think bill rodgers, Frank shorter, Alberto Salazar, (or non-us runners like Steve Jones and Carlos lopes) would not have had times 2-3 minutes faster than their PRs?? Assuming they would, that puts these guys running ~2:05 marathons.
Now, compare that to their times on the track, and it really starts to make you see just how bad we are today at the marathon. We have dozens of guys with equivalent 5k fitness to what these from the late 70s and early 80s ran as their track PRs. Yet, those guys managed to take that track fitness and turn it into modern day 2:05-2:05 level marathoning (if they had super shoes). The modern day 13 flat to 13:15 5k guy can’t even manage to run 5 minute miles over 26.2.
So what’s the deal? I see a few main questions being reasonable assumptive unanswered considerations worth investigating:
Is there something we are doing in training? Does our sednetary lifestyle in general make us “less durable” to manifest our aerobic fitness over longer distances like the marathon?
Maybe the modern day diet with so much sugar makes us so bad at utilizing fat as an energy substrate that we can’t translate fitness into marathon performance?
Lastly, a another very interesting hypothesis worth positing that could turn this question around is the following: Maybe there’s an inherent performance trade off we have never truly understood about track performance and marathon performance, and that we could ask the same question in reverse to the marathon greats of old— ie how is it that Carlos lopes could run 2:06 in normal shoes or Steve Jones run 2:08 in Chicago after going out the first half in 1:01 (imagine how fast that’s be in super shoes) but never manage to a sub 27 or sub 13 minute 5k.
Yes, I know these guys are not US athletes but these are two great examples of incredible marathon performance decades ago from guys who only had mediocre track times. Is there a trade off between the two, and the reason we are so good on the track but relatively bad at the marathon is because we are choosing track performance over marathon performance?
