Way too long!
The longest event for speed skating is the men's 10,000 meters race, which is equivalent to 10 kilometers.
The men's long jump - 8.90 meters set in 1968 at Mexico City.
If you are referring to competition pools, then your answer is Long Course Meters. This course, used in the Olympics, FINA World Championships, and US Summer Nationals, is 50 meters long. If you are referring to longest swimming competition, it's definitely open water swimming. The longest race held in the Olympics is the 25K.
The Marathon
1500m
Yes. The Marathon is second at 42.195 km and the 20 km walk is third.
Depends on what the question refers to: The longest "running" event is the Marathon, but the longest event in terms of distance in the athletics is the Mens 50 kilometre walk (but you certainly aren't allowed to run in that). Alternatively there are a whole series of events that have been included in every Olympics, therefore there is no single longest running event in terms of being at every Olympics.
