Not to be disrespectful but this is a fairly ridiculous take lol. That is not a ton of running to be honest - there are weekend warrior 5K-10K guys in their 40s and 50s who run 50-70 miles per week and you'd have to really be stretching your brain to try to argue that they're not healthy. As with anything, you have to be gradual in conditioning yourself to run that much, but that amount of running is certainly sustainable. I will grant that it's easy to overdo it when first starting running and hurt yourself, but that's a somewhat different topic.

I personally like to take one rest day, but it's not necessary if you adjust the intensity throughout the week to account for never having a full rest day.
