FW6.70 : no display of lactate threshold speed after manually setting LT bpm

Former Member over 4 years ago

hello,

One month ago I switched from the FR630 to the FR645M.

I continue to run with the HRM-run belt, for best accurary.

I use LT automatic calculation.

While I slightly improved my VO2Max, the Lactate Threshold became erratic (very low values).

After a few run I did the LT test which improved the values (both LT heartrate and LT speed) but the heartrate was still far from the one given by my FR630 : 150 instead of 163 bpm.

So i manually entered 163 bpm.

Since then I cannot see the LT speed : for LT the training status info only display the LT bpm which I manually entered.

I dont even see how to deleter that manual entry...

Would someone know what to do ?

Thank you,

Arnaud

Strange the LT speed appeared yesterday evening, and this time it seems reliable. Maybe it needed more runs after setting the LT bpm on manual.

However I still dont know how to set back the LT Bpm to automatic instead of manual. I dont see any options on the watch.

It should be under settings > Physiological Metrics > Auto detection.
