A multi-purpose sports vehicle for the carriage of children which can readily be converted between a wheeled stroller which is pushed by a person jogging or running to a wheeled trailer for convenient towing behind a bicycle or the like. In a third configuration, the wheels are removed and the vehicle can be used as a sled, or "pulk", to be pulled by a dog or a skier. The ready conversion between uses is particularly convenient and economic to the year round sports person.
