Serious: participants are taken "into the heart of India, where you'll traverse every possible micro climate; from metropolis, tropical jungle, arid desert, ancient valleys and the epic coastline." And the whole race is run on three-wheeled Auto Rickshaws (yes, that blue thing). Why? Oh, you know, like... charity. Or something. But no matter the excuse, this race looks like one hundred pounds of fun in a fifty pound bag. I mean, just read through the pimpin' section.The Rickshaw Challenge runs four events per year and the Mumbai Xpress 2009 starts this Friday, July 31. Man, we wish were were signed up.
