Marianne Heading discovered winter endurance racing in 2007, while working as a volunteer for the Yukon Arctic Ultra. This experience inspired her to take up running and go back to the Yukon as a competitor. Since 2007 she has been back to the YAU multiple times, completing both the 100 and 300mile races, in 2011 she became the first European female to complete the 300mile YAU and in 2019 won the 300mile MYUA. Events are not a very regular feature, but other races include the Semi-Raid Reunion, Roveaneimi150, ITI350, Karwendelmarsch and closer to home the Four Inns, the Druids Challenge, Equinox24, run to the castle, Hardmoors55. Being outdoors and enjoying the countryside and wildlife are a higher priority than being fast... luckily! Training runs and walks are often prolonged by a break to watch wildlife and take in the surroundings!
