in general my running was short run off intense bike on Tuesday, long run on Wednesday, middle distance run friday and brick run on either Saturday or Sunday. Miles per week was mostly between 30-40 with max of 48 about 6 weeks ago.
My LT of 250 was based on 40k TT test on Computrainer, measured by former US Postal team member (not that it matters but he knows what he's doing). My AP for 1/2 IM this year was 205 and at my only Olympic race this year was 226 with overall time of 2:02. Thanks
I see a problem right there which is just one reason why people are insisting on more specifics. You're basing your FTP/LT on a CT test. Indoor riding and outdoor riding is different for most people. Now if you were racing on a CT then it might be more relevant.
Secondly, Brian (Desert Dude) and I talked about this a bit over lunch the other day but he raises a very good point about basing IM pacing guidelines
solely off a ~1hr all-out effort. I think 5hr power must be a strong consideration which is why he's asking about your long ride power. Think of it as a fatigue resistance or stamina component. This is often but not always reflected in an individual's power curve. For IM, really flat power curves are a good indication that you can hold a greater % of FTP than someone with who has a drop off between 3 and 5hrs, for example.
I honestly wish that we would come up with something other than a % of FTP when we're talking about long-course pacing. It gets people too focused on 1hr max power. The are other factors that need to be considered.
Also, you need to look at the detail in your power files. Unless I'm reading your posts incorrectly, it sounds like you're making statements based on scrolling through your PT screen.
