Route and Aid stations:
The route runs along the most eastern part of the beach. Competitors are obliged to stay within 15 m of the water, except when there is a distinctly marked corridor. The Start/Final area is on the beach, about 1200 m north of the mouth of the Kamchia River, in front of the bistro Balaton (coordinates 43° 2'5.42"N 27°53'15.22"E). Competitors start southward, cross the mouth of the river, reach the mid-point and run back the same way to the final.
There are 2 distances: 10 and 21.1 km. For the river crossing there will be supplied safety equipment and lifeguards. If, on the event day, the sea is heavy and/ or there is a stream of the river and the sand ford don’t allow safe crossing, the start line will be moved right to the south of the mouth of the river (coordinates 43° 1'15.30"N 27°53'20.50E").
