The 7oaks Triathlon, which is run by members of 7oakstri club, was first held in 1985. Owing to the sudden closure of Sevenoaks Leisure Centre, the event has been changed to a duathlon. There will be two identical run legs, 3.5km in length, through the magnificent Knole park, past Knole House, deer, oak and chestnut trees. The bike leg is an undulating 25km course through picturesque Kent countryside.
