It's good to stay active especially with a bit of a crampy feeling after a hard day but so hard to be motivated! Good for you!

I didn't commute in today because of rain but then that dried up (OF COURSE), so I ran home quickly between lecture and meetings and put in 5 miles of pretty brutal hillwork before coming back. I did it without cycling shorts and still felt great afterwards. That means my sitbones are finally "happy" again.
