Chris and Bob riding from Cape Reinga (top of New Zealand's North Island) to Bluff (bottom of New Zealand's South Island) via a 3000km journey. There are basically only two rules - you cannot accept outside assistance, and you must rest a minimum of six hours a day - other than that it's up to them. They stop, eat, sleep wherever they like - under the stars in sleeping bags, tents, camping grounds, hotels, motels, it's up to them.
Three hundred people started in the last week of February - no entry fee, no prize money, no medals, no speeches, but a margnificigant feeling of achievement no amount of money could buy. I've just remembered the third rule - you have to finish in 30 days.
Did you notice where Chris stores his jandels?
