Create a sports event logo featuring a fluid, energetic design that forms the shape of the number "43" using athletic figures. The athletes should be depicted in various sports actions like running, jumping, and high jumping. The individual athletes should naturally merge and curve to create the slightly distorted form of the number 43. The design should use a predominantly blue color scheme with smooth transitions between shades, ensuring the athletes are fully visible and distinct. The background should be transparent to allow the logo to stand out.
