What if the most dangerous thing you did this weekend was go for a run?



On a bright spring Saturday, hundreds gather in a park as usual for their weekly community 5k run.


An hour later, one of the runners is dead.


The next week a runner training for a 10k event dies. And then another, a half marathon runner…


The police are baffled. The pattern is the same, the deaths can’t be coincidental. Is there a murderer picking off victims one race at a time?


Ten million adults are regular or occasional runners.



Ten million potential victims.



With the next event just announced, as you reach the start line you might just have to run for your life…
