In order to meet the needs of kayaking, the track must meet the following minimum measurement range requirements: the length is 1400 meters (linear distance), the width is 120 meters, the minimum depth is 2 meters, and there are 9 waterways with a width of 9 meters; There is at least one straight river bank beside the channel, and the maximum distance of the buoy line on the outermost channel is 50 meters.

The kayak slalom track is 250-400 meters long, and there are not less than 18 and not more than 25 water gates on the track, among which at least 6-7 reverse water gates are needed, and the distance from the last water gate to the finish line is not less than 15 meters and not more than 25 meters.

Rowing

There should be safety warning waters on both sides of the waterway that are equivalent to the width of the waterway.

Waterways are separated by buoys connected in series. Buoy spacing is10m or12.5m.. The surface of the buoy should be soft and the diameter should not exceed15cm. The colors of buoys in the whole channel are regularly distributed. The buoy is red from the starting point to100m, orange or white from100m to1750m, and red from1750m to the ending point. There should be obvious distance signs every 250 meters on both sides of the whole track.

triathlon

At present, there are three kinds of triathlon: short distance (swimming 0.75km, cycling 20km, running 5km), Olympic distance (swimming 1.5km, cycling 40km, running 10km) and long distance (swimming 4km, cycling 130km, running 30km). The Guangzhou Asian Games adopted the Olympic long-distance running competition. Namely: swimming 1.5km, riding 40km, running 10km, namely: swimming 1.5km, riding 40km, running 10km.

Swimming can be carried out in the wide waters of rivers, lakes and waters. The swimming route can be set into a rectangle or triangle through buoys on the water surface; The starting point and the ending point should be located in the same place; Swimming can take the form of diving at the pier or running into the water from the shore.

The cycling stage requires the track surface to be flat and the width to be not less than 5 meters. The track should include routes with certain technical difficulties, such as slopes and bends, so as to avoid turning back at 180 degrees.

In the operation stage, the track road surface should be smooth, the track width should not be less than 3 meters, there should be no crossing, and other vehicles should be closed. The whole stage must have clear route signs.

During the competition, athletes should carry out swimming stage, swimming-to-bicycle stage, bicycle-to-running stage and running stage in turn according to the project regulations until they reach the finish line to complete the competition.
