Oh he hit you with the, "do your own research." I also like that he posts that on this article about an 81 year old running 130kms. How many of his peers who did 30 minutes can barely walk but he's out there killing it.
At what point did running really far become the thing to aspire too when getting fit?
What about strength? Speed? Flexibility? Agility? Regardless of the evidence, most people are better served doing a good mix of activities and being generalists.
The only reason to run more than 10km is if you like running. Otherwise 5-10km at a decent pace is just a good cheap way to get effective cardio. You should probably stop there and lift something heavy.
I think well-roundedness gets overlooked because our culture is one that lionizes those who push themselves to near-death in a certain specialization, so you get a segment of people pushing themselves harder than is holistically healthy.
I’m not going to convince anyone by pulling a couple references from PubMed. I only suggest you do your own research on extreme sports - and yes, ruining 26 miles nonstop counts as extreme - and come to your own conclusions. If you’re marathoner, I also invite you to investigate the importance of muscle mass in overall health, particularly as one ages. Muscle has a host oh health benefits, even though an extra 20 lbs of upper body muscle mass will kill your long distance running times.

You could at least make a good faith attempt and meet people at least halfway though, right?
FWIW I've read studies saying the same thing- my critique is just with your approach here. You wouldn't believe someone who just waltzed in with a statement and refused to post any references, would you?
