I don't think there is something wrong with "我昨天在公园里(没)跑步", it's ok, I understand it fully and I also could say like it. ------------------------------------------------------------------------------------------------------------------------------------------ I agree above. "我昨天在公園沒跑步" emphasize in 跑步, it means that you were in the park,but not running. "我昨天沒在公園跑步" emphasize in 在公園, it probably means that you were not in the park at all. Hope u like my answer

我昨天在公园里跑步 right but 我昨天在公园里没跑步 sound weird... you should say 我昨天没有在公园里跑步！

Regarding the rules of 没 It has 2 primary uses, one to refer to a past tense action, and to mean lacking possession of something. 1。 你昨天看电视了没有？A: 没有 (Did you watch TV last night? [I] did not.) 2。你有照片吗？A: (我)没有 (Do you have a picture? [I] don't.) When using 没(有) in connection with an action, it needs to go before the verb. In your sentence, the biggest difference you can make with the same basic words is indicating what you didn't do. In one permutation, you might say that yesterday you did not go running in the park. In another, you might say that you were in the park, but you didn't do any running. Your usage of 没 is correct, it just depends on which of the two sentences you meant to say.

我昨天在公园里跑步 it's right. i ran in the park yesterday. 我昨天在公园里没跑步 also right.when you use this expression, you want to say, i am in the park yesterday, but didn't ran, maybe play balls, maybe just walking etc.. 我昨天没在公园里跑步.also right, when you say this sentence, you meat you maybe ran yesterday,but not in the park, maybe somewhere else the rule for "没' is very confused in chinese, you should pay more attention to the position of "在公园里”or "结婚" in below example , "没' is before that, or after that for instance, ”我去年没结婚', means, you didn't get married last year, maybe the year before last,maybe this year, maybe you are still single "我没在去年结婚",means, you are married, but not in the year before last

I think this sentence is right. 我昨天在公园里没跑步。It means "I didn't run in the park, may be I did other things." 我昨天没在公园里跑步。It means "I ran yesterday, but not in the park."
