The Boat Race, the challenge between Oxford and Cambridge

The referee clasps an 1829 gold coin, around him the tension is sky high. Tens of thousands of spectators lining the banks of the Thames hold their breath as they wait for the toss. It’s the turn of the challenger, the president of the losing club from the previous race, to choose heads or tails. Whoever wins chooses which side of the river for their team, Surrey or Middlesex, according to the weather. An advantage that may decide the race.
