Race walking competitions
Competitive race-walking events typically require a lot of stamina- the longest, such as the 50km Olympic event, are longer than a marathon. These events also require attention to technique to avoid a "lifting" violation. In the Olympics, there are the 50km and 20km events; both men and women compete in the 20km event, which starts from a standstill.Being this active is great for your healthy lifestyle.
IAAF rules clearly outline the differences between walking and running. A competitor that crosses the boundary between the two will receive a "lifting" infraction; the front foot must be firmly on the ground when the rear foot is lifted, and the front leg has to be straight when the foot touches the ground. Judges can warn competitors by showing them a yellow paddle; one judge cannot give repeated warnings to a single walker.
When a walker doesn't comply with the rules, a red card is sent to the head judge. Three red cards from different judges will disqualify the competitor. During the final 100 meters of a track race, if a competitor flagrantly violates the rules, they can be disqualified, even if they have not earned any red cards. Rules for the 50km , men's only event are the same.
The Olympic events are road-based, which is why competitors there are not eligible for world records. Race-walking competitions usually begin and end in the stadium. Competitors must qualify on time and for their country's Olympic team; each country is allowed only three competitors per race-walking event. As is the case with all races, the event ends when the walker's torso moves over the finish line.
