New Human-Powered World Hour Record
jesterpilot writes "Last weekend, the limit of human propulsion was pushed another kilometer. At the 2006 Dempsey-MacCready One Hour Record Attempts on the Nissan track in Arizona, Fred Markham set a new World Hour Record by cranking 85,4 km in a fully faired recumbent bicycle. This is about 1 km more than Sam Whittinghams 2004 record.
Noting Fred's age of fifty years, it seems the boundaries of human propulsion are not even close yet.
Read a report of the decisive runs on Rob English' diary."
Allowing recumbents in road racing would entirely change the nature of the sport. When riding an "upright" bicycle, riding behind close behind another competitor requires about 1/3 less effort. (Sheltering.)
However, nobody is stupid enough just to let everyone else sit on their wheel for a 200Km race. Instead echelons are formed where riders take turn in front, doing their share of the work. Eventually break groups form, and hopefully the smaller group can organize better and gain an advantage.
Of course, if you're in a break group with all your own teammates, organizing isn't a problem. But most of the time you're with competitors. So you have to work *with* your opponents, yet still beat them. This leads to all sorts of interesting tactics.
If road racing turned to recumbents, such tactics would virtually disappear due to the shelter advantage being reduced to minimal. It would, in essence, become a mass start time trial instead of a road race as we know it today.
This is why the UCI does not allow recumbents: It'd be a different sport.
