do you run on grass or pavement?

Pavement. And by pavement I mean the boardwalk.

that is better than pavement, less force on the knees, with the force distributing through the wood.

Yes, and yes.

Also, the the use of the verb run in this case should be “have run”, not “have ran”.

Definitely - and a great atmosphere day or night - I just don't want to accused of cheating. The boardwalk could be considered the original vaporfly

I like to run on flat trail, that's my favourite surface. A short and dry grass is a great surface but often it is wet, slippery and not flat at all, turning it into a cross country session.

But in the winter, it's almost always running in the night, so not on trail, but on pavement. And cratered and irregular pavement are a bad surface. Without to mention you can't have work out on pavements. Circulation lights, cross walks, cars parked on the pavement, all of that is annoying.

I've never run on grass. We don't have grass here. Only in some parks but it's not exactly allowed to run on grass there because there are footpaths for walking/running. In addition to that in winter time they are so wet and slippery that running on grass could be kind of dangerous.

For about 3-4 months of the year it is dark before I go to work and dark when I get home so don't really have any option but to run on pavements. There is a park near me with a 1 mile flat loop which is good for workouts but it's still a hard surface unfortunately. At the weekends I try to get out onto a trail if possible for long runs.

I'd do all 90% of my training on grass or smooth trail if I could. Sadly, there is almost no grass around me because of people's needs to turn every vacant field into a golf course (you can't run on them, you're not part of the elite rich fatty club who likes whacking tiny balls around - and even if you were still no, it might make you not a fatty, strip mall, or more neighborhoods (thats a neutral thing, housing is sky high). Most of the trails near me are rooty or rocky - not ideal for doing more than jogging. I'd prefer hilly parks designed for running, or golf courses left vacant (yet maintained) or turned into parks for exercisers.[

You can work on the road or any type of pavement so long as the flow of traffic is light enough. For light, you can wear a headlamp. Do you run on the sidewalks? Do you not have residential roads (think neighborhoods) or something low trafficked near you?

I agree that doing a workout on most sidewalks is next to impossible, you have to look for solutions that allow you to run on the road.

I run on the sidewalks when there is traffic but I have noticed that most sidewalk are in worst shape than road, more cratered , with much less renovation, also I don't like much the elevation change at each garage door. And some people park their cars on the sidewalk and you have to find a way. I also occasionally run on bycycle lane when there is nobody.

I only run on road pavement at night when the public light is on and with little traffic but I often end up on the sidewalk, and you can't do anything other than moderate run for mileage. Even neighbourhood always seem to have cars coming right at the same time than me and you have to look for each crossing and be careful.

I have access near my home to some nice trail in the forest and in the day I only run there. Softer, big straight lines, trees to ease wind/sun, and only a few points where you have to be careful (a road pass through the forest with light traffic). That road is closed to cars every sunday with barriers so there is a 1.2km straight line road with perfect asphalt that I can use the Sunday.

Err, no. The second part of the sentence is in the past tense.

Why do so many Americans get their tenses wrong? Is it because of the English-as-a-second-language-on-social-media influence?

Also, why do so many Americans and non-native English speakers chop off the end of adverbs to turn them into nouns?

e.g. "It fit me". It should be "It fitted me". Its in the past tense. You are describing something that happened previously. cf also "I'm tan" (its tanned, its a process not a descriptor) or "I'm chill" (chilled).

I won't even attempt to explain why gotten should be used in the past tense and preferably at the end of a sentence, as its lost its preposition and is otherwise meaningless without correct sentence positioning.

In answer to the question, I prefer to run on trails if possible, although grass is good for developing knee lift and pavements are good for correct knee positioning and foot plant, if you have an injury.

All surfaces.

Yes, I run on the grass or the pavement.

Sometimes I run on other surfaces too...

Now I'm curious about indoor sandals.

Keep it on the 'Crete

I'm about 60% flat,dirt or gravel trails, 30% asphalt, 10% other (including grass, treadmill, mountain trails). If I could I'd increase the grass percentage.
