From July 23 to July 31. WHERE IS IT HAPPENING? The Yumenoshima Park Archery Field in Tokyo. HOW DID WE GET HERE? Archery was first included in the second edition of the Olympics in 1900 and in three more Games afterwards. Yet too many local variations led to archery being dropped from the Olympic programme. After the global body of archery was formed, the sport eventually made a return to the Olympics at Munich 1972, with recurve events being the accepted form. At present, 64 men and 64 women compete in the individual, team and mixed team archery programme at the Olympics. The team events were introduced in 1988. WELL FANCY THAT Before releasing each arrow, archers must calm their heart rate, increase their concentration and overcome their nerves. The physical and emotional tension inspires some to perform at their best while others struggle in the face of the unforgiving pressure. Wind can be kryptonite to the best of archers, with the merest breath able to send a cleanly shot arrow wide of the target.
