The Lion Heart Ultra Cross Triathlon is an energy-draining long-distance race. It's 3 km of swimming in open sea waters, overcoming various terrains in 116 km of mountain biking, and an energy-sapping, picturesque 21 km trail run in the forests of Strandzha mountain. A challenge that excites the adventurous, sounds impossible to the masses, and sets out to unlock the unlimited human potential.
