Starting with a 2.5 m Tempo is a bad idea

As I looked at my plan to run a 2.5 m tempo every Tuesday I realized that did not make sense. Instead I'm going to start with a 1 m tempo and build up to a 2 m by the end of base training. After the Thanksgiving CU 5K Turkey Trot I'll begin running Thursday at lunch time. I'm going to build up to 4 m by January 1 because this will take me to the base of my 90 second hill. I plan on starting with 3 hill repeats on week 1 building up to 8 hill repeats on week 6 for Thursday lunchtime runs. I will not do any hill repeats during base training ie 2006.
