I calculated the big hills starting at mile 16 on the Boston course. The first is .25 miles at 2.5% grade. There is a .5 mile hill at 2%grade and heart break is 2.3 percent for .75 miles. So I plan to start my hill repeats during the week as well as continuing the Punta Gorda Bridge in the long runs and adding the Ringling Bridge in Sarasota as additional training.
We are doing the Sarasota half marathon which incorporates the Ringling Bridge. I would guess the Ringling Bridge is about a .4mile climb pretty steep so it should provide good training.
In addition I am incorporating leg strength training once a week with single leg lunges, reverse lunges. forward lunges, and squats.
Only time will tell how it all pans out. This week a 20 mile run in Punta Gorda
