In any kind of sport or game, whether it is for casual exercise or for competition, every one should know the “rules of the game”. Most of the competitive sports have a set of Rules and Regulations in order to maintain good order and efficient conduct of a game or an event. Without these rules and regulations, the event will never be called a “sports discipline”.
If a person would like to engage in any kind of sport discipline, the first thing to do is to find out its rules and regulations. The Internet is full of information on this matter and all you need to do is to input/type the topic you want to research on your browser or in Google and everything is there for you to read and download. It is very easy and fast.
By following these rules and regulations, it will be easier for you to appreciate and improve on the sport/game you want to learn or concentrate in. Do not wait for the other practitioners/athletes or opponents to remind or warn you about its rules and regulations. Prevent yourself in an embarassing situation with the pros.
In running, there are rules and regulations that should be followed also. However, they are very easy to comprehend and follow as they all boil down to these words—Common Sense, Fair Play, Honesty, and Courtesy. There are also running events that are very unique from the usual 5K, 10K, 21K or Marathon Races where you have strict duties and responsibilities of support crew and pacers. (Note: There should be no Support Crew and/or Pacers in Marathon/42K Races). Usually, support crew and pacers are included in ultra running events and they have some responsibilities and restrictions on how they would be able to support their runners. If you want to know more of these, you can browse on the rules and regulations of the Badwater Ultramarathon (for Ultra Road Races) and/or the Western States 100-Mile Endurance Run (for Ultra Mountain Trail Runs).
At present, I am now trying to read every word of the Rules and Regulations of a Triathlon Event as published in Triathlon Resources in the Internet. They are very long and very specific but knowing the details would be the first step to really appreciate the sport.
I hope I am on the right direction!
