Detroit Marathon deaths show running is a serious business

Three runners died during the Detroit Marathon in the US this weekend. The oldest of the trio was reportedly 65, the second 36 and the youngest just 26 (he collapsed after finishing the half-marathon).
The causes of death have yet to be confirmed, although in the case of the oldest entrant, it was apparently the result of head injuries after he fell.
Either way, three deaths in one race is unacceptable and hopefully we can learn from this to prevent similar tragedies in the future.
