I have picked up a formal training plan for half marathon to keep myself both organised and have an idea how to train. My scientific mind needs some training plan - I have done 10.8 mi run and 5K in 20 minutes (on a treadmill) without prior training. Happy I got away without injuries those times.
The training plan is pretty much 4/5 runs a week with the mileage currently being ~25 mpw and I am trying to increase it in 10% increments (currently 3rd week in training plan). Workouts on Thursdays, long runs on Sundays and easy runs in between with some rest days.
My question is how and when I can start hill running without adding risks? Should I swap out a workout or a long run for a hill run? Does it even matter if all I want is to get fitter for hills and maybe participate in some races?
