I have two previously torn meniscuses and a torn patellar tendon. I don’t run a ton (my workout program does agility training for cardio), but I can just decide to go run a sub 30m 5k with no problems.

It definitely wasn’t always this way. I used to have to tap after 10 minutes due to the knee pain. Until one day I thought, “Maybe I’m doing something wrong,” so I did some research.

Turns out I was doing something wrong. I was running with the same form I used for walking, which is a heel to toe movement, and taking similar strides. This is actually the opposite of what you’re supposed to do.

The first mistake I was making is the long steps. When running, your goal should be to never let your feet extend more than an inch or so further forward than your hips. Walking is more of a controlled fall, but with running you’re propelling yourself forward.

The second mistake I was making is fully straightening my knees. Your knees should always be bent a little bit. And the third was landing on my heel.

When running, you want your ankles and knees to act like a spring. The ball of your foot should hit the ground first with your foot pointed somewhat down. then you absorb the initial impact by dropping your heel and bending your knees a bit. Think of it like crumple zones in a car. You don’t want all of the impact transferred instantly, which is what happens if you land with a straight leg.

Then you push forward with the foot that’s down, and repeat for the other leg. The faster you go, the more you’ll need to lean forward to keep hitting the ground with the ball of your foot.

It does take a bit of getting used to in order for it to be muscle memory, but it should help if your issue is incorrect form.

    You were landing with a straight leg?!!? Were you insane?

    Also don’t rip on heel striking. Lots of us do it and it’s perfectly ok as part your stride mechanics.

    Your mechanics will vary as a function of your relative speed and heel striking is a natural movement at the upper end. What it sounds like you were doing was overstriding - you were lengthening your stride to try gain speed rather than increasing your turnover. Get those feet moving quickly and that will keep your weight centered.

    Your stride will lengthen as you speed up with quick turnover, but the heel contact will establish foot placement without a full transfer of weight. The weight transfer occurs (the stance portion of your stride) as your hips glide over the foot. When you are doing this correctly you glide smoothly without a lot of bouncing up and down. If you have vertical movement, shorten your stride until you are gliding.
