For years Kate Rawles has combined adventure with environmental awareness – in the most eco-friendly ways she can. In 2016, aged 53, she built herself a bamboo bicycle and set out on an epic journey through South America, exploring biodiversity - and why losing it is as great a threat as climate change. Over 13 months she travelled the length of the Andes, 8288 miles, from Colombia to Cape Horn, through high mountains, salt flats, rainforest, desert and tundra.

She talks to Andrew Dickens about her adventures and cooks up Huevos Rancheros on the Food & Travel Stage.

Huevos Ranchero (Ranchers Eggs) is a hearty egg dish that has been eaten on Mexican farmhouses and Ranches since the 16th Century. The dish consists of fried eggs with fried or charred corn or flour tortillas topped with a spicy salsa made of tomatoes, chili peppers and onions. The dish has since spread across South America and the World with any number of delicious variations.
