Distance to go:
Ben and Tarka will cover 1800 miles starting from Scott's Terra Nova Hut at the edge of Antarctica to the South Pole and back to the coast again. That's equivalent to 69 back-to-back marathons hauling up to 200kg each (the weight of roughly two adult men) of kit and supplies necessary to survive.
Distances here are shown in statute miles.
How long is your toothbrush?
As the flight to Antarctica draws closer, Ben and Tarka are finishing off the last of their expedition prep including packing food, customising their skis and shaving unnecessary weight off kit wherever possible.
