It's time for Six Nations to break out. January slipped away quickly and now it's Six Nations and its many heads. And the Sevens start up again with Round 4 in Wellington, New Zealand.

The European Nations Cup, sometimes referred to as the Six Nations B, starts the second leg of its competition played over two years.

In South Africa the Varsity Cup starts. It is played in four sections, each its own competition - the Cup, the Shield, the Under-20 and the Residences.
