What to do on MTB DH rides with PM??

Hi all,

I have a power meter in my MTB. It is on on all my rides, but I am starting to think about some possible errors on calculating effort and calories.

For regular XC rides, it should be ok, but as soon as things start getting more complicated in descends, then it is not. On Enduro rides, it is counting the descends as no power at all, but it could be difficult ride and HR at 170bpm. And if I go just to DH rides, then it is even worst, as it can count only 10w for a full ride of several minutes at 190bpm.

Anyone know if disabling the PM will calculate only on HR and it will be a better calculation?.

Best regards,

Jose

That is a very interesting question. I think it is certainly better not to connect the power sensor in this case. Then mainly the heart rate is used to assess performance. Speed, time and distance could perhaps also be included. I don't know to what extent and whether the cadence is assessed at all.

Cadence in DH is not really an issue.

But, anyone knows if there is a way to force GArmin to recalculate an activity using HRM data as prevalence over PM??

OT:
maybe the new Edge MTB takes this issue into account…?

I hope so, so I will wait for the update on the Edge 1050, as it has the hardware for new metrics.
