I ended up modifying my plans quite a bit last week (see below). There were days when I was not quite up to running the full distance I had planned, and some days I didn't feel like running at all. I was able to adjust my schedule and still obtain my two goals for the week: 1) 55 total miles 2) a long run of at least 35 miles on Saturday
Below is my updated schedule for March with my running plans for this week.
Two main goals of the week:
1) 65 total miles
2) Back-to-Back Weekend Long Runs of 30 miles Saturday and 15 miles Sunday
Lesson here is, don't worry too much about the day-to-day goals as long as you can set and reach weekly or maybe even monthly goals for yourself.
