First TT in the books.  Overall a good showing with small room for improvements.http://www.strava.com/activities/115624799/overview

10 miles
23:15 / 25.8 mph
294 AP/ 294 NP  VI =1.00

Good enough for 8th overall and 2nd in the Men 18-34 Cat 4/5.  I placed right about where I thought I would given the competition.

First half was 296 AP and second half was 297 AP, the turn around was 0 watts for 9 seconds which brought my AP down to 294.

I was closer to 291 AP at the 3/4 point, but had enough left in the tank (too much) and pushed it up to 294 by averaging 336 for the last 2 minutes.

I've got another TT next weekend...likely about 1.5-2 minutes longer in duration, but I should be able to squeeze out 300 I think.  It's point to point, so I don't lose any watts as there is no turn around. 

Oooohhhh, maybe I should pick your brain about this a little bit.  How long are you in Florida?  

As you noted, HR for a given RPE is higher in the heat and humidity.  What about power?  Do you notice that your power output is lower or unaffected by the heat and humidity?  If you were to train in a hot, humid environment, but then race in a cooler, dry environment (with minimal time to acclimate....i.e. no time to do test riding/running), would you stick with the power output that you'd trained for in the heat/humidity, increase it slightly, or decrease it slightly?  

I attempted Week 8's Threshold 1 ride today, but my legs were incredibly fatigued, so I decided not to dig myself any bigger hole and just kept the power around 85% instead of 95%.  Hopefully they'll come around by Thursday. 

I find that heat and humidity has less of an impact on the bike. For me. My power to HR is very predictable and I see it doesn't change much. I just did a 3hr ride and my watts to HR were almost indentical at the start and end of the ride while the temperature and humidity went up considerably. I ran before and my HR/pace was good. I bet if I did the run now I would be 45sec/mile slower at the same HR Maybe it's because the speed/air flow compensates for it more than on the run On race day, on the bike, I find heat/humidity is less of a factor. The bike is usually early in the day, heat is probably less a factor on HIM and shorter. If it's really hot (like Vegas WC) then yes, I would back off a few watts. If it's cooler, I would not increase my watts. Very much a personal choice but I rather bank that extra energy for the run. The run is another story. You get off the bike and the wall of heat/humidity hits you. This is when you know you have to back off the pace. It's 11AM-noon it's starting to get hot In a HIM, there is lots of time to spend that extra energy you may have. Keep it. If you still have it at the mid point of the run, go for it.

Heat and humidity usually only impacts me on the bike during long climbs...where airflow is similar to running.  At 15+ mph, not so much.

Heat and humidity doesn't bother me too much since it's what I typically train in.  I was mostly just curious how to race in a place that's cool and dry after training in the heat and humidity!  I think I'll stick with the power I dial in during training and bank any extra I might have for the run.  Oh, the run...
