I like to do a mp run 10 days before marathons. After a 1 mile warm up, I did 8 miles at my original goal mp, then 1 mile cool down. Well, I found out that although my calf is now healthy, so I should be able to finish the marathon, the last few weeks of nursing my injury has caused me to lose my speed. It looks like I will have to change my goal mp from 6:50, which I ran today, to 7:10 if I want to have a good race. Now to get serious about the taper.
