Week 4 of Phase IV is going fine. I had to rest on Sunday due to travel, so I ran long on Monday, and I did my threshold run today on the road. It was 3 + 2 miles with 2 minutes rest. Paces were very good at 6:16/mile average. Almost 10 miles per day is necessary though to finish on 60 miles for the week, and there is one more hard run.
