Ready to DIE?! That's right, it wouldn't be an <em>expert survival</em> race with a nice little chance of death and doom, now would it? Your best bets are probably heart attack or heat stroke (depending on weather conditions) rather than getting stabbed by your own broken ribs or ripped apart by piranhas, but the obstacles are as extreme as modern safety regulations would allow. They include tire-rolling, climbing over a net-covered school bus, tightropes, shipping crates filled with cold water, and a lot more. For a less extreme version, try the half-distance race (6 km). Contrary to what the name implies, women are welcome, too. Register on their website.
