Hi. I am using a BKool Go trainer in conjunction with a Garmin Edge 520. The Edge accepts different ways of working out the HR info and include a % of LTHR which is the one I find most useful. I can't find a way of making the BKool show anything other than a % of maximum HR. If I use the on-screen zone info it isn't the same as that in my Garmin and it is irritating. Does anyone know of any way of getting the HR based on % of Lactate threshold? I do use the power meter on BKool and I have noticed that the zones using the Power figures gained from a power test do not match those zones which use % of max. Has anyone encountered this problem and could provide a solution?
