Jack thank you sir, yes makes sense, perfect.  Yes and definitely trying to replicate as I’m doing mountain races (Ultra Tour Beaufortain 7k meters vert in 110k mid-July).

The only other quick follow-up is I’m 2 weeks out from race, do you still recommend to do them on stair-stepper vs uphill treadmill, I have both but wonder if its risky for fatigue doing stair stepper vs a slightly less muscle impact on uphill treadmill.  I don’t have enough vert outside my house to do on trail over next couple weeks – so gym it is!

Thanks again for all the great content.
