My problem with sciatica is now dormant, so I've been able to touch training. If I walk or stand too much, my right SI joint is still a little sore, which can sometimes cause pain in my legs. I've looked at how SI joint problems get into sciatica and there seems to be at least two mechanisms. The piriform muscle crosses the Si joint and may be stimulated, which in turn affects the sciatic nerve running below it (or in some people, it penetrates the piriform muscle). The second method is that if the Si joint becomes inflamed, it releases inflammatory enzymes (Cytokines) can cross the nearby sciatic nerve.

Fortunately, none of my bike rides, arm cycles, or major sports activities trained with resistance bands caused any symptoms.

So, I've been getting harder and harder on all of these activities lately and it feels good. Yesterday, I made a 30-minute relaxing ring and then traveled with the local group for three hours. We walked to the end of the Redwood Retreat southwest of Morgan Hill, one of my favorite routes. It was a quick pace and was very pleasant most of the time, but got a little hot at the end. It's the time of year to wear a lighter layer and remember to bring ice water in my hydrated bladder.
