In the shadows

I just had the cleverest idea ever...to run late today, once the sun is all up, and to see how it feels in order to prepare for what I'll face next saturday at the triathlon...
I was so mistaken, it was the most stupid thing I've ever done in my life! Running 10K felt like a full marathon, and I could only run beneath the shadows of the trees, once I was out in the sun light, I'd started to feel terrible...
What is going to happen next saturday? Will I be able to run all those 10K after my swim and bike affair? Will I feel like I'll faint? Will I be invincible, mainly caused b the overload of carbs and the intake of several GU gels?
I wish I could have a decision vote within the organization commitee of the triathlon, and to ask for mercy by making my category start the race at 7:00!!! But since it seems impossible, it all depends on fate.
Nothing is known today, only that in 1 week I will already be an olympic triathlete!!!
