The position is drawn, but Black has to play accurately to get his half-share of the point, as can be seen from the fact Stockfish10 for quite some time reckons White is winning (Komodo10 quickly recognises the game should be a draw).
60.Kd3 Kc6 61.Ke4 Kd6
Too slow is 61...Kc4?, viz 62.Kxe5 Kd3 63.Kf5 Ke2 64.Kxg5 Kf2 65.Kxh4 Kxg2 66.Kg4 etc.
62.Kf5 Kd5 63.Kxg5

63...e4?
Black draws by 63...Kd4 64.Kxh4 Ke3 65.Kg5 Kf2 66.h4 Kxg2 67.h5 Kxf3 68.h6 Kg2 69.h7 f3 70.h8=Q f2, reaching a position the Nalimov endgame tablebase confirms is drawn.
White could try the tricky 66.Kf5!? but the engines show the position is still drawn with correct play, ie 66...Kxg2 67.Ke4 (not 67.Kxe5? Kxf3 68.h4 Ke3 69.h5 f3 70.h6 f2 71.h7 f1=Q 72.h8=Q Qa1+) Kg3! (not 67...Kxh3 68.Kxe5 Kg3 69.Ke4 etc) 68.h4! (68.Kxe5 transposes to 67.Kxe5?) Kxh4 69.Kxe5 Kg5 70.Ke4 Kg6! 71.Kxf4 Kf6 - the final position is drawn because, with his pawn on f3, the white king needs to get to e5, f5 or g5 to force the pawn home (for a fuller explanation, see: https://beauchess.blogspot.com/2020/02/the-power-of-two-squares.html)
64.fxe4+ Kxe4 65.Kxh4 Ke3 66.Kg4 Kf2 67.Kxf4 1-0
