Hi there I sound wheezing at night from last few weeks doc done test for asthma all normal, no cough, running 4-5 times a week so what could be?

Upper obstruction. Do you wheeze when breathing out or breathing in? If the latter, it would point to obstruction higher up instead of in the lungs. If you are overweight. Weight reduction may help a great deal. If not, see an allergist or ent.
