Without trying to repeat other runners´comments: Having lived here for over three months, it´s a good time (spring) of the year to run the Buenos Aires Marathon. You get a good 'tour' of the city. It´s a big-city marathon. Having run more than 60 marathons in the States, crowd support is not like New York or Boston. More like San Francisco or Miami. I ran my fastest marathon in 10 years. Flat as a pancake. Like Houston.

Course is a wonderful tour through the city. Great volunteers. Carry gel with you - water stops every 5k, but only a few food stations with bananas and oranges. Watch for cars - volunteers and police block the streets, but BA drivers get very impatient. Overall a great city to visit and a fast race.

I agree with all of the comments below. And at $40, definitely one of the cheaper marathons going. Things seem a bit unorganized at the expo and at the start, but somehow, it all fell together. Flat course got me a 30-minute PR!

It's a good marathon for time. There aren't so many people and the weather is cool (14c).
The only problem is the traffic that sometimes don't respect the runners....

Friendly and well organized marathon. Internet/fax booking worked out OK. The course offers a beautiful city tour and is pretty flat. Few spectators but enthusiastic. Water stations every 5Km including Gatorade and banana/orange in the second half. Goodies include nice medal and Coolmax t-shirt. Very good marathon, ideal for a personal record and a great city to visit. Definitely one to run.
