Sep.20 (GMM) Heikki Kovalainen has agreed to join Mark Webber's famously arduous annual outdoor challenge for charity later this year.



The Renault driver is the first of Webber's grand prix contemporaries to be persuaded to travel to Tasmania in mid November for the five-day endurance event, according to the local Mercury newspaper.



Just prior to embarking on the Australian cycle, kayak, trek, abseil and swimming odyssey, Finland's Kovalainen has already signed up to run in the famous 42km New York City marathon in November.
