We spoke to Sarah Tunstall, GB mountain runner who bases herself in France for periods throughout the season. Sarah has had considerable success on the mountain running circuit over more than a decade. She finished 3rd in the European Championships back in 2008 and, more recently, has finished 2nd and 3rd at the World Championships and won the World Cup. In 2019 she won Grossglockner and Drei Zinnen. However, despite achieving great success over a number of years she has suffered from injuries which have forced her to rethink her approach to training. Here she tells us what she's learned from her setbacks and how she's found the right balance.
