Zip, zero, nada. That's how many miles I've run in the last 7 days. Surprisingly I'm ok with it (so far). I had a familiar pain during my last run (which happened to be a 5k trail race). The last time I had a similar pain I didn't run for 5-6 weeks so I decided rest was best.
My self diagnosis, by the way, was some sort of QL (quadratus lumborum) strain. Kind of like a lower back strain...but it's not. A little deeper and off to the side.
On a more positive note, I got a TON of mountain biking in over the last week. Woohoo!
