I think you’re a big biker if I recall. I used to have high cholesterol years ago , but completely modified my diet and eat mainly healthy. Once I started running , the levels came down in combination with the diet . I avg 20-25 miles per week now. During my marathon days(I ran 7) , I was doing 45-55 miles per week. Point being.. if you modify what you eat and vigorously exercise , it’ll come down
