Sunday the 19th.
Following Ewen's advice, I am easing back gradually, did 52K the week of 6-12 and 55K this past week. No hamstring pain at all.
Included three halfway decent workouts this week, intervals at about 4:30/k pace on Wednesday, 11k with 10 150m hills on Friday and a 5k tempo run today at 4:50.
If I can do a 10K tempo run next Sunday and a 15K one the Sunday after that, maybe I will be ok for the Sendai Half on May 10. I don't want to race it, just run it all the way at a moderately good pace.
Hope I can get a live feed of Boston tomorrow night.
