It's a cow's life - nothing but grazing and milking, milking and grazing. It's not a bad life really, for an ordinary cow, but it's just not enough for Marta. Marta is different (she's orange, for a start). Marta wants something more. She wants to go. She wants to ride. She wants to feel the wind in her face, the pedals under her hooves. She wants to win the big bike race. And when Marta wants something she makes it happen. But first she has to build a bicycle. And then she has to learn to ride it. Is there enough time before the race?
