Analysing terrain data
The exposure grade describes the potential consequences of falling or slipping off the path.
Low Exposure: The path is on completely flat land and potential injury is limited to falling over.
Medium Exposure: The trail contains some obstacles such as outcroppings and rock which could cause injury.
High Exposure: Some trail sections have exposed ledges or steep ascents/descents where falling could cause serious injury.
Extreme Exposure: Some trail sections are extremely exposed where falling will almost certainly result in serious injury or death.
17 days, solo unsupported world-first running expedition across the Bolivian Andes, completed November 2018 by Jenny Tough.
Excerpt from the story, originally published in Sidetracked Magazine Volume 14: "Fourteen days ago, in a small town near the Peruvian border, I stood at the start line, the base of the Bolivian Andes, sheltering from torrents of freezing rain that curtained the town.
I stared at the washed-out mud roads that led out of the village, searching for a reason to abandon the whole thing entirely.
For the first time I could remember, I was literally paralysed by fear, standing under a tin roof and refusing to take even the first few steps.
I had two options.
The first, a 12-hour, rickety bus ride back to La Paz, which actually seemed just as uncomfortable as running the first segment to my next chance to quit; the second, four passes over 5,000m, a forecast for stormy weather throughout, and no civilisation aside from coca growers and gold mines.
I chose the muddy trail over the bus ride home, but it was pretty close for a moment." - Jenny Tough <a href="https://www.sidetracked.com">Read the full story and more like this in the latest issue of Sidetracked magazine and on Sidetracked.com</a> FATMAP Explore Members get 15% off any single issues or subscription.
