Olympics-New Zealand’s Walker fails in Rio BMX bid (Reuters)
London Olympics BMX silver medallist Sarah Walker has failed to qualify for the Rio de Janeiro Games after injury hampered the New Zealander’s last chance of making the starting line in August. The 27-year-old injured her shoulder in training at the world championships in Colombia and was only able to finish fifth in each of her three qualifying races, failing to advance as one of the final 20 riders making it to the quarter-finals. Walker, who finished fourth at the Beijing Games, has been plagued by injury since the last Olympics and needed surgery to fix a badly broken arm suffered while training in February.
