The wonderful initiative "Children's Sports Festival" by our Olympic triple jump champion Tereza Marinova celebrated its 10th edition on May 25th. Bulgaria's incubator of sports talent, the National Sports Academy "Vasil Levski," hosted the event, and the Minister of Youth and Sports, Krasen Kralev, opened the children's athletics tournament. Nearly 700 children between 6 and 12 years old competed in the disciplines of 40m, 60m, 150m, 600m sprints, standing long jump, and 4x50m mixed relay. The participation was international, creating a highly competitive environment where the youngsters felt like part of the big sport. A crucial element of the overall professional atmosphere during the tournament was providing enough suitable water for the young athletes. As is well-known, proper hydration is of immense importance for good coordination and muscle condition, regulating body temperature, preventing blood clots, and for mental endurance during competitions. In their care for the children's excellent physical and mental form, the organizers chose RILANA spring water. Thanks to its nearly neutral pH, low sodium level, and total mineralization below 86 mg/l, RILANA is an excellent solution for the good hydration of young athletes.
