Obviously you run the risk of freezing your tail off but thankfully the course they have is through nice and quiet streets with small hills. The fact you can stay inside the gym before and race the race if it's real cold helps alot.

Would run this race again.

There is no better way to sight see one of the most amazing cities in the world. Overall the event is very well run and is the experience of a lifetime! There isn't really any post-race party, they do their best to just direct you out of the park.

This race was one of the most amazing experiences of my lifetime. I have never seen so much crowd support in a city, and felt so much love as I ran alongside thousands of other runners. I would do it again in a heartbeat!
