The Tarawera Trail Marathon in New Zealand is 50k across forests, mountains, lakes and waterfalls. It's a serious race that attracts some of the world's best runners and in 2015 the race will include a re-fuelling station offering Devonshire cream teas to athletes. The cream teas will be severed in the local landmark of Buried Village, where the original village was destroyed by mud from the 1886 Mt Tarawera eruption.
Clearly the organisers have good taste!
