Please check my out and back calibration

Post by noahpb »

Hi John,

I've had my PowerPod for a couple of months. I started with a standard calibration ride and my power numbers seemed high. So I spent some time trying to manually edit the profile, but finally decided to do an out and back calibration yesterday.

I had to ride a decent distance to get to where I could do the calibration ride and I was slightly confused about the LED status when I got there, but I think I got an acceptable ride in. It was pretty windy, hard to avoid this in San Francisco.

Details about me: 46yo, 6' tall, 140lbs. Fitness level at the bottom of serious amateur range (I thought my FTP was around 175 but perhaps it's a little higher). Riding a Cannondale Slate road/gravel bike with 42mm 650B slick tires. EDIT: PowerPod mounted on the standard clamp that came with it.

After the ride, I did a Check Calibration on the ride and noticed that the ride position was set to "hoods" although I thought I set it to "hoods, elbows bent" before the calibration. I created another profile with that setting updated since that is my usual position.

I'd appreciate any feedback you can provide. Thanks!

Noah

If possible please post a ride file that was made after your cal ride. That will make things easy to check.

Thank you John, here's my ride after the calibration (9 miles). Puttering around in the same area for a bit and then heading home.

It seems like there was also a ride recorded as I was heading to the place where I did the calibration. Let me know if that would be useful.

Hi John, I'd love to get your input on this. I'm hoping to get out on a long ride this weekend and it would be great to have it sorted out before then. Thanks!

It looks like you had a tail wind on the return portion of your ride.

As long as this is the case, everything is fine.

Both of your cal rides are within a few % of each other, so you are fine.

Enjoy your ride!
