I've finished my 46-mile week with no problem. My 13.5-mile long run was hard: it was a hot day on the gravel path of Tom Sawyer State Park, which also has some elevation change, and I ran the mile loop 13 and a half times. But I recovered well by the end of the week, and my Sunday 6-miler felt easy, even a bit hungover.

Now onto the 50-mile week. I'll bump up the long run to 15 miles, and my weekday runs to 7.

Finished my week with 42 miles, with a 12-mile long run and an 8-mile run in the Parklands at Esther's M pace. That was 7:20/mile in 86 degrees from 10:30 to 12 with lots of solar radiation. It was tiring, but entirely doable. It doesn't reveal too much about my fitness, only that it is not horrible. The hardest part was the heat.

Now on to a 46-mile week, which will be accomplished by 5 x 6.5 and a 13.5-mile long run. Slowly getting there... 60-mile weeks are in shooting distance.
