Being an athlete from the host nation in an Olympic year can be the proverbial double-edged sword.
There are, of course, undoubted benefits that go with this status - not having to travel across the globe to compete, familiarity with the host city and its venues, the rapturous support of the people of your nation and the vast majority of spectators watching your chosen event.
But there can be a significant downside too. If evidence is needed, simply recall the outrageous levels of pressure placed on Cathy Freeman before the Sydney Games in 2000 not only to win her 400 metres track event, but also to be an Australian sporting ambassador, a symbol of the Games as a whole, and even a figure of national reconciliation.
No wonder then that when she crossed the finish line in triumph, the weight of the moment literally took her legs from under her, and Freeman sat, drained, barely able to move as she accepted the congratulations of her rivals.
