Which Spinervals for a desert isle?

SK---No cheating on your gears! Those hard parts of UHG (haha, what an accurate acroynm) are only 4 minutes long!! Do you have Hillacious? Now there's a quad burner :-)

Hillacious has an awful lot of rest after each interval. I had to really keep an eye on my HR to make sure it didn't drop too far in the four minute rest sections.

I do like the simulated rolling hills.
