Thanks for the interest! So I did my last FTP test today so am pretty much set in terms of where I am going to be fitness-wise. I have one more week of higher quantity before beginning my 2-week taper on Monday.

Let's hope this + a good nutrition plan + some luck with get me there!

Swim: can do 1000scy sets (open turns) in 16:15, so roughly a 1:38/100 pace. Will be wearing a swim skin (let's say taking 2-3sec/100 off) but also will be in an open water washing machine. Best reasonable case is 1:12 for the IM swim.
Bike: FTP of 270, weight of 63.5kg, so ftp/kg of 4.25, which I'm reasonable happy with. Unfortunately IMTX is a pretty flat course so only headline watts matter Will be riding a P2 w/ carbon wheels + wheel cover, aero road helmet, pretty aggressive position. Aiming to ride at 72-73% of FTP so ~195 watts, which I think will put me in around 4:50-4:55 with no mechanicals. (I rode Miami 70.3 in 2:25 w/ worse position, no wheel cover, and a rear tire at 70psi @ 190W)
Run: I'm in solid 2:40-low open marathon shape (long runs @ 6:30 pace, 10-mile pace runs @ 6:10 pace). So according to Daniel's VDOT table, at 75-80%FT, my IM projected time is somewhere around 3:10-3:20.

3 projected slots at IMTX, with bubble boy being somewhere around 9:30 every year. If everything works out perfectly, I'll be in the 9:20's. If that doesn't get me a slot, I'll still be satisfied.

I listened (but didn't quite follow) everyone's advice for Boston. I ended up biking really hard the two days prior to the race and then running Boston in 3:14, with essentially a 20-mile long run around 7-min pace and a 6 mile jog around 8/8:30-min pace. High-fived cute babies, drank a beer w/ friends on Heartbreak, took pictures with people along the way. Never enjoyed a run more and felt fantastic. Picked up training within 2 days and haven't noticed any decline in performance.

I'm nervous, excited, relieved all at the same time. Can't wait.
