  • All the people saying “yes” are incorrect. Running on pavement and running on trails exert different strains on the body, but not less. The tendency in road runners is to end up with tibial stress fractures, and in trail runners it is metatarsal stress fractures, but the injury rates are similar. Trail running requires stronger stabilizer muscles (primarily gluteus medius) to maintain knee health in the long term, but this is a problem for both as well.

    Use good shoes, strength train your gluteus medius and calves, do most of your miles at an easy pace, and you’ll be running for decades, regardless of your chosen surface. You might even change it up and do both!

    (My credentials are that i am an ultramarathoner and have run half a dozen races between 26.2 and 50 miles, on pavement and trail, and i have been coached by a professional ultra runner for several seasons.)

    It’s crazy how much height subconsciously influences our opinions of each other. I’m tall enough that most men don’t look down at me, and I’m widely respected professionally. Men listen when i talk in meetings, and it’s very easy to sell my ideas to people. My shorter coworkers who are more talented than i am struggle to gain respect.

    My ex is 5’2" and i have very strong feelings of cute aggression towards her, and have to consciously remind myself to consider her opinions sometimes. It doesn’t help that she acted like a child a lot during our relationship 😒










  • You can lose about 7% of your bodyweight in a single day before it starts to impair your performance. For a 180 lb person, that means you can lose almost 13 lbs of sweat. The average human stores about a day’s worth of calories in muscle glycogen. Once you burn through that, you’ll experience something called “hitting the wall”. People who aren’t trained for this will quite literally just… stop working. They’ll fall over and not be able to move. With training, you can make your body better at burning fat to keep your muscles moving even when you surpass the limits of normal human endurance.
