I'm done grass running. It is now injuring me.

You are supposed to hop, not run, on grass.

the snakes agree you should not run on the grass. They don't like being stepped on.

Ahh, thank you, Grasshopper!

Almost happened with a copperhead on a park trail a number of years back but I only was running on grass soccer fields that had occasional curious deer and a few rambunctious dogs (got knocked over twice).

I was doing plyos in a grass field and sprained my knee pretty badly. A month off, a year later and plenty of rehab, I still feel it from time to time. The uneven/ lumpy surface can very easily create issues with the knee ligaments. I’d imagine running on a flattened ball field or golf course wouldnt cause the same issues, but running in circles isn’t for me.

I have a similar mindset to get off the concrete. Just seek generally softer surfaces. Woodchip trails, dirt roads, single track trails, tracks. All my runs tend to connect “soft spots” with a bit of pavement in between, but I don’t run on the grass next to the sidewalk, I just stick to the sidewalk now.

I’ve run my share of grass.

I've seen a few studies (links below )that suggest when running on softer surfaces, your body compensates by running with a stiffer leg. Therefore, there isn't any reduction in injury risk by running on grass. You're just shifting the load to different parts of your body.

Running on softer surfaces is just as hard on your body as running on pavement

Do Softer Running Surfaces Really Reduce Injury? | TrainingPeaks

Doctor Jeff Sankoff offers new findings that may contradict our understanding of running surface and injury.

He would have said "keep it on the crete"

Probably because with modern shoes you're running on a softer surface already.

Different surfaces have their pros and cons. That's why you should include them all.

Kentucky bluegrass or tall fescue?

It's a hybrid of Kentucky Bluegrass, Featherbed Bent, and Northern California Sensemilia.

Yeah, I may gravitate to that concept (knew about it for years but never really embraced it) eventually when my knee gets a bit more recovery.

I have recently seen the literature suggesting the soft surface, stiffer leg studies may suggest increased stresses through the knees and hips. I was thinking my success on grass was due to the variability of surface keeping from repetitive more uniform footstrike impact patterns on hard flat surfaces that is linked to overuse injuries (of which I've had many in years past). I guess that circles back to the concept of mixing it up with different surfaces, which I have resisted embracing but may need to reconsider it now.

Different gait.

Grass can be longer or shorter, and it can hide little dips or bumps in the ground where you really make contact. Did you have a little misstep on grass, preceding your injury?
If so, you may have subtly changed your gait on grass.

I knew a guy bought a used car once. Five years later, BAM, herpes.

My worst injury ever was on grass. Ran onto what a thought was a tiny pile of leaves, turned out they were covering up a small hole. Nasty ankle sprain that partially tore/strained the retinaculum holding my peroneal tendons in place. Recovery took forever and years later I'm still occasionally feel it, even with tons of PT and strengthening. So I stick to roads now.

30+ years ago my HS XC coach liked to say that running on grass was good for you until you roll an ankle, and you will roll your ankle.
