24 Weeks expedition Training Plan – Hilly Terrain

Hi everybody,
just wanting to catch your thoughts on the “Run/Hike on hilly terrain” sessions included in this Training Plan.

The plan wants me to run/hike below AeT (in my case 143bpm) with a vertical gain of about 1000f (300m) for about 2h.
My problem is, that in the area where I live its either up-up-up oder flat. So I’m having trouble following these recommendations.
If I do an easy circuit next to my house it’ll be about 14km in length and 900m (3000ft) of altitude gaining. I won’t be running much if I don’t exceed 143bpm (except the downhill passages). Of course I can hike up and run down but is this still the same training benefit? I’m sorry but hiking just doesn’t feel right.
I normally do a bit of mountain running and so far my strategy was to run as long as I don’t exceed lactate threshold (172) at which point I’d stark walking until my heart rate goes down enough to restart running. I’ve done some marathon distances following this strategy but for aerobic capacity training this does not really fit the rules.

Do you have any recommendations that could help me ?

Regards

Eike

p.S. I wont use stairs, gyms or what not ! I live and love the mountains. No way i’m training indoors ! sorry
