Boulder 70.3?

10 degrees would be great!!!  20 would be AWESOME!!  but it looks like highs in the mid to upper 90s.

I'm preparing mentally for the heat

StMaas - 2011-07-27 7:17 AM 93 degrees during the run was an eye opener last year.  I'm going sock-less this year, and probably will use arm coolers on the run as well 

Do arm coolers really work?  They seem just like arm warmers to me (when I have looked at them) and that they would make me sweat more ( I do that way to well on my own).

I was skeptical when I first saw them, but have rea  few differnet reviews about how they work, and the science seems logical.  I got a free pair from Doc Amanda Stevens at a Clinic I attended, I'm going to try them one of my remianing runs before next weekend.

I'll be right there with ya. I'm wearing my sleeveless wetsuit, no matter what.

To those that are definitely wearing wetsuits regardless of temperature:

Why do you wear one?  Is it the buoyancy or do you actually get that much speed increase from wearing one?  Is it just the psychological factor associated?  I come from a swimming background and I've actually found that on warm days it's more of a pain to wear a wetsuit.  My core body temperature gets too high and I'm already sweating coming out of the water.  I'd personally rather save that exertion for the bike.  I'm not judging or doing a poll, just curious is all.  Good luck to all of you- I'm going to be in Chicago the day of this race so no bouncing @ Lefthand for me this year!

I recently picked up a sleeveless wetsuit and will definitely be wearing it. Likewise from a swimming background, I dont need the 'free float' but will take it for the net energy savings to be had. While I got the sleeveless for better shoudler rotation/mobility, I have also found that the large arm gussets help with upper body cooling, and its a bit easier to get out of.

Also I have compared it to swimming in the tri top only, the wetsuit is definitely more comfortable and there's less drag.  Having said all that, I will probably get a swim skin for next year, if I can figure out how to sneak it into the budget!

Current forecasts suggest that the temps shouldn't be too bad on Sunday.

Also, I went out for a big brick session on the bike & run courses a couple of days ago, in the middle of the day, and noticed that the dirt roads that make up almost all of the run course seem to help in the heat/sun. As soon as I left the dam path and rejoined the tarmac road, it immediately felt much warmer, due to the heat that was radiating from the road. So now I've stopped grumbling about the fact that the run will not be on regular roads.

I rode a loop of the course yesterday and ended up with 3 flats before making it back to my car - ugh!!  One thorn puncture, then broken glass.  And now, need a whole new tire.  But at least it was my training wheel set.

Not to scare anyone, but might wanna make sure you've got your flat repair stuff ready for the weekend.
