A human traveling on a bicycle at low to medium speeds of around 10–15 mph (15–25 km/h) uses only the energy required to walk. Air drag, which is proportional to the square of speed, requires dramatically higher power outputs as speeds increase. If the rider is sitting upright,HP0-Y20 the rider's body creates about 75% of the total drag of the bicycle/rider combination. Drag can be reduced by seating the rider in a supine position or a prone position, 70-431 thus creating a recumbent bicycle or human powered vehicle. Drag can also be reduced by covering the bicycle with an aerodynamic fairing.In addition, 70-620 the carbon dioxide generated in the production and transportation of the food required by the bicyclist, per mile traveled, is less than 1/10th that generated by energy efficient cars.

I love this cross for sure. I am trying to participate there every single year, however I have missed one in 2009. That's the type of activity when all running people are like a huge family. I mean it is not spending your time by the computer or playing games, it is real rest. It doesn't matter that you get tired. I mean it is a real paradise. Thanks for the great article by the way.
