Document Summary
David zabriskie wr in time trial in over 20 km stretch, he averaged a speed of. It"s as bad as other sports, in terms of doping. Close to 80 km/h speeds on those hpv (human powered vehicles) but impractical. Difference between mass start and individual time trial: No draft in time trial so its all about aerodynamics. Group vs individual riding is different because riding in a group, you use less energy. David zabriskie holds the record over 20 km at almost 55 km/h average speed during a flat ride. An elite rider will do the same distance in 5:26 less. Elite rider gets bigger savings in terms of percentage of total time, this is just by form and not by equipment. Need to have certain flexibility to be able to make use of this position, or else they won"t be able to bring their legs up to pedal.
