Paleo is not a list of foods. It is matching one's diet/lifestyle with one's genes. The paleo part is an aid to knowing how to match one's diet/lifestyle with one's genes. It is only an aid, a starting point. You have to work out the details because no one knows your genetic structure with regard to your diet, but you can figure it out with trial and error.
I run long distances. Some "paleo" guru says that isn't paleo. I don't give a fig leaf what some "paleo" guru says. I love running and I have seen with my own eyes (via TV) bushmen running down game and tiring them to exhaustion and killing them. They ran for like 11 miles to catch and tire that animal. Running seems paleo to me, as much as sprinting and weight lifting.
It is very difficult to work out the details of your genetic dietary needs when you are doing things that are grossly out of line with your genes, like grains and legumes. It is like trying to catch a signal when there is a lot of noise. You have to reduce the noise a lot in order to hear any signal. Then, once you have some kind of signal, you can fine tune the signal. But if you have too much noise (like too many grains and legumes) and can't hear any signal, then fine tuning is useless.
