|Tens of thousands of people compete in the 10K race in six heats|
|It is crucial for runners to train even for the 10K race|
|A 2014 study found 1/3 of runners didn't train for the 10K|
To not train for any race is wishful thinking and disrespecting one's body by pushing it to extremes it is not prepared for.
It would be interesting to know if other 10K races around the world have seen serious incidents. If it's only in Hong Kong, then there is a serious problem about health education in the city.
