Thanks to all who helped me with my decision. There's no pain in my calf when I'm walking around, but yesterday I could definitely feel tightness going up the stairs in my building. I think Anne at Run DMZ put it best: "Don't fall victim to the numbers game if you sense an injury approaching!" The numbers game was the toughest part of the decision. For me, a fifty mile week is a big deal. I really struggled when it came to the 50 mile weeks during my last training cycle for Long Beach. This time, not so much. Last week, with the exception of the last two or three miles of my 20 miler, 48 was not that difficult. I was looking forward to 50 plus this week. Instead, I gave my calf yesterday off, and have canceled today's 16 miler. Everything is feeling pretty good today, so I'll try to cap the week off with something around 9 or 10 miles tomorrow. We'll see how it goes. Bottom line is I want to make sure I'm okay for my Half Marathon next Sunday.
On another front, the Injinjis are treating me well. I used them on my last run (Thursday's six miles) and I have no major complaints about them. I want to wear them on one long run (probably next week's Half Marathon, and then I'll file my complete review. My teaser for now though can be summed up this way: "What socks?"
