The Color Run is one of the most joyful and colourful events of the year in the Romanian capital. The concept is simple: thousands of people dressed in white run a 5km course, getting sprayed with paints of all colours every inch of the way. Except this is the night version, which is a bit different. Participants dress in black (everyone is given a Color Run t-shirt) and sprayed with flourescent powdered paint before being soaked with foam. The event is followed by a party in PIata Constitutiei.<br /> <br /> You can sign up on the day, until 18:00.
