Strava estimated power vs real

I’ve always wondered if the Strava estimated power was close to real power. So on a couple of specific segments I’ve run my phone using Strava and my Garmin using a power meter so that I can compare.

You can see from the screenshots below the differences.

In summary for smaller segments it was within 5%, drifing out to 13% on a 20 minute section, so you would assume it would drift further out for a full ride, something I will try in the near future. Interesting side note that the phone often gave me a second quicker time….

  Segment time Real Power Estimated Power Difference
Langbar Reverse 20:55 246 214 -13%
Roker Lane 02:30 367 356 -3%
Crekeld Lane 05:41 299 288 -4%

Syncing OneDrive to an SD Card on Windows 10

My previous method stopped working with Windows 10, fortunately I found another workaround on the Microsoft Forums as follows:

It looks like the OneDrive client in the RTM version of Windows 10 does not allow syncing OneDrive to an SD card via the empty NTFS folder method if there isn’t enough free space on the C: drive for the data to be synced. There is a simple workaround from GiovanniSantoroJunior:

From the Disk Management console, follow these steps:
1. Right-click Disk Management and then click Create VHD. Follow the prompts that appear.
2. Right-click the new disk and then click Initialize Disk. Click OK.
3. Right-click the new disk and then click New Simple Volume (or select a different volume type, if available). Follow the prompts that appear.

Follow these instructions to set your new VHD to automount when Windows boots.
