Martin Strel is planning on swimming the entire length of the amazon river over the course of the next 722 days. If you thought that I had some crazy ideas up my sleeves you’d better take a look at This Website and see what this guy is planning on doing… Swimming the entire length of the Amazon River!

It amounts to around 90 km of swimming each day. The funny things is that this isn’t a joke he’s serious. He’s swum the entire Danube River (Europe), the entire Mississippi River (USA) and the entire Yangtze River (China) and the entire Parana River (Argentina). He’s also swum 504 kilometers in 84 hours, continuously!

I guess his speed has got to be on pace for ~4 km/hour in standing water if he plans to get those big distances on moving water.
