FTP Test

Former Member

Today I tried to do the FTP Test with my Edge 520 plus.

After the warmup, I stayed as good as I could within the upper and lower limit of each intervall.

When the 3rd intervall was over (225-245 watt) the garmin popped up a message saying "the FTP value could not be calculated. Please try again".

I tried a second time. This time the same message came after the second intervall.

What can be the reason why the garmin cannot calculate the FTP value?

Should I consider anything special during the intervalls?

  • I had a similar experience a while back,  maybe a couple of firmware updates ago. I'm obviously not as persistent as you - I didn't try again!  I'll be interested to see if anyone can shed some light ...

    I’m facing similar issue, except that I got the error post cool down of 2mins and the workout completed. Were you able to get it? If so, how?

  • Hi, 

    Was it solved for one of you already and how? I tried it a couple of times now, but it keeps giving the same error message. I am curious if there is a version which I should run to solve this. Kind regards and keep healthy and cycling.
