The distance between the start and the finish is 45 km as the crow flies.
Issyk-KulRace is held from May to September inclusive. About 80 small tributaries feed the Issyk-Kul, in the west the Chu River flows nearby, which gives it a part of its water in the spring, and the lake does not have drains. The length of the reservoir is 182 km, width - 58 km, and the maximum depth of the lake is 702 m. Therefore, only such giants as Baikal, the Caspian Sea, African Tanganyika and Nyasa are deeper than Issyk-Kul, as well as South American San Martin. The unique moderate maritime climate prevails in the lake. There are no severe frosts and exhausting heat here, in winter the air temperature does not go lower than -2 - -6 degrees, and in the middle of July it remains at the comfortable + 17. The sun shines on the coast of Issyk-Kul for about 2,700 hours a year, for comparison: in Moscow this figure is a thousand hours less.
Weather conditions for the swim are assessed by the organizers using forecasts from several sources and reported to swimmers on the eve of the start.
The organizers select suitable weather for swimmers, depending on their level. Trust the organizers, wait for the "start" command.
There can also be such a weather, in which no swims are held, yachts do not go out to the bay, and normal people do not go outside. In this case, you will have to wait for the weather to get better, which may take several days, or, on the contrary, shift the start a few days ahead until the storm has come. The swim can take a few days, or even a week.
According to weather conditions, the swim can begin (and end) at any time. The organizers want to start swimming after breakfast and finish by dinner, just like you want. Instead, the beginning may take place at lunchtime, and you will have reached the finish only by the night. If this happened, believe that it was better for you. Security first and foremost, and the organizers are pursuing your interests only as the second priority.
