A man has died during a 100km charity walk in Perth.
The man, who was taking part in the 100km Oxfam Trailwalker endurance event, collapsed in Swan View yesterday afternoon and was unable to be revived, a St John Ambulance spokesman told AAP.
It appears he suffered cardiac arrest during the first day of the event, which asks teams of four to walk a 100km bush trail within 48 hours to raise money.
