Tell us about your training.
I train six days per week. Four workouts are focused, two workouts are recovery. Focused workouts included one hill repeat workout, one run at marathon pace, and one long run at 30 seconds slower then marathon pace. My training also included weight training for the first 10 weeks of my 20 week training plan.
Definitely need to include hill repeat workouts for this race and also work on efficient downhill running that does not force breaking with your knees or feet.
