apart from having a good buggy and loads of courage, this video clearly shows how important it is to keep the speed you have gained by ,slipstreaming, streamlining, not making the cart less stable by rocking back and forth ( whoever had that idea has a lot to learn ) and taking the quickest line ( staying in a straight line as much as possible , straightening the bends as much as possible ). Speed is hard to get and oh so easy to lose
