You could extent prototype method:

var oldMouseStart = $.ui.draggable.prototype._mouseStart;
$.ui.draggable.prototype._mouseStart = function (event, overrideHandle, noActivation) {
    this._trigger("beforeStart", event, this._uiHash());
    oldMouseStart.apply(this, [event, overrideHandle, noActivation]);
};

$("#draggable").draggable({
    beforeStart: function () {
        console.log('beforeStart::');
    }
});
