Don't mind Sand - he's a chump

But he's
our chump.Tex, you might try some stretching when you're away from the running (e.g., at night) - just some gentle stretches such as getting the arms over your head and stretching out the sides. Maybe it would help, too, to do some planks, either regular ones or the side planks to build the obliques. The overall idea is to build a stronger core to support your run training. Good luck with it!

After a bit more snow last night (on top of the ice that's out there), I went to the parking garage this morning and ran the stairs for 30 minutes. Legs felt a little mushy afterwords, which is kind of a good feeling after that workout ...I know I worked the legs over good.
