Course bologna time trial

Hello
can anyone explain this, when you look in the conpanion app at the track BOLOGNA TIME TRIAL, it says 256hm
when you look at those who run the course, it seems to be about 756hm or something like that, how does this happen?

it depends how many laps they do, I guess?

Only 1 on both

There’s a large disparity between advertised elevation and the actual elevation when a course is run.
Some of it depends on how your treadmill handles elevation. If in increases in half a percent at a time it’ll be more accurate.
