PRACTICAL SPORTS

Professional single-day race distances may be as long as 180 miles (290 km). Courses may run from place to place or comprise one or more laps of a circuit; some courses combine both, i.e., taking the riders from a starting place and then finishing with several laps of a circuit (usually to ensure a good spectacle for spectators at the finish). 

Individual time trial (ITT) is an event in which cyclists race alone against the clock on flat or rolling terrain, or up a mountain road. 

Stage races consist of several races, or stages, ridden consecutively. The competitor with the lowest cumulative time to complete all stages is declared the overall, or general classification (GC),

races are very long single stage events where the race clock continuously runs from start to finish. They usually last several days and the riders take breaks on their own schedules, with the winner being the first one to cross the finish line. 

based on the aerodynamic benefit of drafting, whereby a rider can significantly reduce the required pedal effort by closely following in the slipstream of the rider in front. Riding in the main field, or peloton, can save as much as 40% of the energy employed in forward motion when compared to riding alone.

Usually a rider or group of riders will try to break from the peloton by attacking and riding ahead to reduce the number of contenders for the win. 

Races often feature difficult sections such as tough climbs, fast descents, and sometimes technical surfaces - Stronger riders are able to drop weaker riders during such sections.

As well as exceptional fitness, successful riders must develop excellent bike handling skills in order to ride at high speeds in close quarters with other riders. Individual riders can reach speeds of 110 km/h (68 mph) while descending winding mountain roads and may reach 60–80 km/h (37–50 mph) level speeds during the final sprint to the finish line.
