Wow, I just went and did it and just enjoyed the ride.

.

This is my first year with a power meter. What is an appropriate VI for Lake Tahoe full IM? My targets right now are 74% NP, 69% AP with a resulting 1.07 VI; does this seem about right? Also 84% of FTP HR.

Yeah but tell him about all the time you spent agonizing over your gearing months before the race and then the hundreds of times you rode the course hills on your Velotrons before you enjoyed the ride except for the 8 times you had to stop and urinate due to over hydration;)

I knew my gearing from the start and stay with it, 50/34 11/32. I rode the course a few times on the velotron. And I drank no water which having to stop 8 times to pee was really weird. :)

I'm really curious about the course itself and how that plays into VI. If a flat course should be 1.04(?) what is Tahoe with 8,000 +- feet of climbing?
On a flat course one would be aiming for a VI a good bit less than 1.04 ........more like 1.01 to 1.02ish. Remember, Ap gets you down the road while NP fatigues you. A higher VI will likely give you a faster bike split on a hillier course because it cuts down on the time you spend going super slowly up the hills.

Genetics load the gun, lifestyle pulls the trigger.

Why does gearing matter for AP or NP? I wasn't aware that played into the calculation at all

Is there not a certified one uploaded on there already?
