Hey Red, I ran the Marathon (or is it a half marathon? 10 kilometers), I actually finished before someone else, which is great.
The path went uphill for some time, which was pretty hard, but then most of the race was downhill and that was a bit better. I think I handled the run pretty well, I had to walk some of it because of the heat (30+ celcius).
Since they had to close the streets for some hours, traffic was chaotic; there were cars trying to cross the street we were running while the police were trying to organize the flow. At one intesection a policeman actually asked me to wait for a bit so some cars could ge through. I was like, er, it's a race, I can't stop!
Well anyways, it was the first time I ran a marathon and I think it was a great experience, I'll definitely do it again.
