It is way underrated. Brisk walk will get you the same benefits without the risk of joint damage.

I used to be in that community and a significant portion of them were recovered addicts of one kind or another. Could be more relevant than their long runs.

I don’t know but the distance runners I know gererally run 8-10 miles per day as their maintenance workout and then add more when they are in training for a marathon or iron man or something like that. A 5K seems like nothing and most of them won’t even do a 5K because it disrupts their usual routine.

Walking is healthy exercise and supports a wide range of muscles

-The crap some runners use as snacks along the run for quick energy is filled with chemicals that are probably terrible for the gut

-Some runners are into healthy eating, others eat a ton of junk and use running to burn. I wonder if those who developed cancer were more likely to eat crap or pseudo healthy energizing snacks and protein snacks.

This sounds most plausible to me. It's like the opposite of calorie restriction.

I ran 6 between 26-33.

At 55, my back is so jacked from all of the years I spent running.

Thankfully, clean colonscopy- no polyps at age 50.

I think it’s more likely due to runners being told minor blood was due to excessive e running, etc abs since they are healthy, thin not having them in to investigate.

I’m not si sure it’s the actual running causing it.

My best guess as a former marathoner is that the correlation is diet related. The fuel required to run and train at these distances means lots of carbs that can be easily digested. Think sports drinks, energy gels, energy bars, pasta, high glycemic fruits, pasta, potatoes, bagels and bread, etc. There are lots of runners that think they can eat and drink what they want because they run off the calories. Runners that may typically consume 1500-2000 calories a day will often consume between 4000-6000 calories a day on a long training run or race. The majority of those calories are carbs.

Dean Karnazes, the most famous ultra marathoner, wrote in his book about eating an entire pizza on a long run. He admits he used to have a terrible diet while training and racing. He has now completely changed his eating because he realized how bad his body felt from it.

I would guess diet and inflammation combined are contributing to this phenomenon.

This would explain why so many of the people with young onset colon cancer are not overweight/obese.
