In October, Rachel and Stefan are going to take part in the Global Challenge race. Rachel is from wales and Stefan poland. They're going to sail round the world in a yacht. People normally travel west to east because the wind goes, but Rachel and Stefan are going to travel east to west. They're going to travel fifty-six thousand kms and it's going to take about a hundred and fifty day. They are going to be twelve yachts in the race with eighteen people on each yacht. Each yacht is twenty-two long and the people can only take one kilo of luggage each.
