Beginning in week 8 there is some cardio followed by sprints followed by more cardio.

The middle part seems like just HIT intervals. I haven’t sprinted in a long while and don’t want to risk the groin muscle that finally quit bothering me bothering me again or a hamstring injury. Is just high intensity cycling or a ski-erg ok?

Yes. I believe in the accompanying PDF we actually recommend against running for the sprints unless someone is well trained already. I like cycling or the air bike personally.
