Clearing up a misconception on Parker Valby's training.

Webb was a great runner because he was a talented runner and trained as a runner, not because he was a swimmer.

I am very likey in the minority but I would rather fly on an ellipicial than do a long slow easy run. The feeling of going fast is very excellerating to me.

Out of curiosity, what are PV intensites on the arc trainer? I am very curious what incline, resistance and spm she does her workouts at.

I have done workouts before on the arc trainer when I was injured or the roads were too bad to run fast on (covered in snow, ice and/or slush). I did workouts going by minutes such as 30 minutes hard tempo and 8X4 minutes. I hit ~185 spm for the 30 minute tempo at 20 incline and 33 resistance.

Maybe I misunderstood something, but I think it was always clear that PV cross-trains a lot and runs 2-3 times a week, quite demanding by the way. There's no misunderstanding about that.
The fact that top national runners don't use this concept and just do more running miles doesn't mean that this concept can't work for even better times.
The comparison with triathletes is not quite correct in my opinion, because they usually train for a race that lasts a little under two hours up to eight hours or more (depending on the distance), whereas PV runs much shorter and at a higher intensity.
We all know that a high-intensity workout such as 8-10 x 1k or 10 x 400 (mile pace; by the way: no triathlete does this) requires a recovery time of at least 48 hours. It is interesting to see how far you can push PV's concept. Example week: 2 days with double threshold (threshold on the arc trainer in the morning, threshold run in the afternoon) plus 1 day of intervals on the track. That's 3 runs plus a lot of cross-training. Why not?

To be clear: cross-training on the other days of the week.

These are different skill sets. Elite swimmers have more muscle mass, a large torso and are usually tall(Michael Phelps is 6'4"). You won't see any overlap between Elite swimmers and runners. Elite runners are skinny with long legs. But someone who is a well-trained swimmer will still have that aerobic development.

Valby is a Generational Athlete.

We have a "multi-sport" athlete sighting.

What brand is the trainer? Is it a life fitness arc trainer?

NXN entry was based on home in CT. She was already attending HS in FL.

This is absolutely true. I'm older than most in this situation but due to injury and aches and pains I moved half of my running to an arc and increased the time spent training and I am in much better shape than I was even 6 months ago. To think that a world class talent couldn't use the arc as more than a supplement to training and more of a replacement of running is just naive.

If you think it would be that effective for a "world class talent" perhaps you could name some who train by this method?

Lia Thomas could have been a great 5-10k runner but her cack is to big.

It isn't as effective. That is why she 1 minute behind the best while Blanks is only 20 seconds behind.

Depends on whether you think Parker Valby is world class or not.

Look...I realize you like to debate points...most of which are not debateable as they require proving a negative....but you're also a bit of a bube.

So what do you attribute Valby's success thus far?

Meh, horses for courses. The athlete still has to physically fit the sport, even if they are doing work that isn't entirely specific.

Webb was a great runner, but he was also a very solid swimmer. I believe he was close to junior national cuts in 5 events as a freshman in high school. If he stayed on that trajectory, he probably would have received a Division 1 scholarship, but realistically would not have had a chance to make the Olympics in swimming. I do believe all the swimming (I think he swam for Machine Aquatics in NOVA which was more a high yardage team) gave him an amazing aerobic engine. We’ll never know what type of runner he would have been with no swimming.

My sister is a good example. She swam for a high yardage team and didn’t even run her freshman year, but did a 5:12 in her PE class mile spring of her freshman year. The teacher, who was also the CC coach, told her she needed to come out for the team. With only 25ish miles per week her sophomore year, but swimming often 3+ hours per day with doubles, she made Kinney Championships as a sophomore. She would absolutely not be the runner she was without all that swimming. She swam all through high school and both swam and ran in college (although that was very difficult at a top Division 1 school). But no, not every great swimmer will be a good runner.
