Fri - Today I want you to do a short tempo run. Warm up 2-3 miles and do 3 X 5 min at marathon pace with 2 min recovery in between. You really have to focus on the pace. Keep in mind that this is marathon pace and will feel very easy for 5 minutes at a time. Visualize yourself in the race and make sure you are running a controlled pace. 2-4 miles cool down. This should not be a difficult run, instead it should tell you how the pace is going to feel during the race. And, keep in mind, this is only a snipped of it. Don't run 3:15 marathon pace!
