low power reading

Yesterday I rode an out and back loop, actually a lollipop shape. I had a severe headwind, more of a quartering headwind actually. I felt as if I were working my ass off! The tailwind felt fantastic on the way back. Looking at my files it shows an avg power of 195 watts and NP of 219 watts on the way back but only an avg power of 128 and NP of 146 on the way out! I didn't think the power was accurate on the way out so I stopped and started a new file. In addition I can usually ride at about 270 watts, but its early season for me.
Can anyone look at a file and tell what the problem might be?

Thanks

The 7 mile ride is the headwind, the 8 mile ride is the tailwind.

Thanks.

You need to add these files as "attachments" to this forum.

The 7 mile ride is the windy ride.
The 8 mile ride is the tailwind.

Thanks
