Great week of training. Had a really good balance of mileage and workouts. Looking for another 5-6 really good weeks like this. The alteration workout felt excellent. It provided a good mix of "speed" and endurance. Next time I'm going to try 600/1000 and increase a few more miles on that workout. About 9 weeks to go until Twin Cities. Next week I will be racing a 10 mile on Tuesday and then a track 5k in Brazil on Sunday. I'm going to use them both as hard workouts and not really change much from my marathon plans.
