Vaidas Zlabys

Hailing from Lithuania, he should be an inspiration to all of us. Holding down a full time job and living in an urban life, he is a pure amateur runner but that hasn’t stopped him from taking on the world elites at ultra trail races and posting some very impressive results and he’s going from strength to strength, year after year.
