7 weeks ago I stopped running. In that time I've done (in reverse chrono order)
6 weeks ago I ran 7 miles with the TMs on the River Trail and roller skied (skate) three out of 5 days
4 weeks ago I walked about 3 miles flagging a trail and I roller skied again once (skate)
3 weeks ago I walked about 3 miles cutting a trail
2 weeks ago I walked about 5 miles marking Blackstrap Hell and about 7 miles over two days picking up Blackstrap Hell
This past week I ran/walked three different times, between 2 and 4 miles.
That's not much activity for 7 weeks. The skate roller skiing aggravated my butt so I stopped. One of the days that I picked up Blackstrap Hell aggravated my butt. But the run/walking this past week was fine. I really felt like I could see the light at the end of the tunnel.
Then I skate skied 9 miles yesterday at Pineland. It was great to get out. But within 1-2 hours of finishing, my piriformis was on fire. And it's been on fire all day today. Skating seems to be the absolute worst activity for this injury. This really sucks.
