Emergency room doctor Shane Naidoo saw Chrystal Rinehold on the ground and helped her, then accompanied her to a hospital. After, he completed the race.

When a woman collapsed during a half-marathon in New Jersey over the weekend, an emergency room physician who also happened to be running in the race sprang into action – then he went back to cross the finish line.

A Cardiff Half Marathon runner who collapsed at the finish line has died in what organisers have described as a ‘terrible tragedy’. The runner, who has not been named, was rushed to hospital but later pronounced dead after completing the UK’s second largest half marathon.

A Run 4 Wales spokeswoman said in a statement that it was with "deep regret" that they confirmed the death of one of this year’s participants at the annual Cardiff Half Marathon
