Ian MacNairn came into the path of ultrarunning by accident. His initial steps as a trail-runner and mountain man announced the end of his recovery from near-fatal injury. Ian pursued rehabilitation and running as a health scientist, using his own case as an example to study the physical, mental and social transformations that occur in pursuit of ultra-endurance. Ian has continued down the path of exploration, studying ultrarunning as an anthropologist and student of medicine.

He has published over 75 articles and pieces of writing in national and international publications on running, sport, culture, and exploration. In 2013, Ian founded Kids Run Canada – an organization with over 35 events across Canada working to promote play and well-being by bringing youth outdoors to explore through trail-running.

Trails and racing

Ian has raced across Canada and internationally. He has won or landed on the podium in many events ranging from 5K to 193K. He has been the record holder for numerous ultramarathons and unsupported trail runs in Canada. In addition to xact nutrition Ian is supported by The North Face, Smartwool, and Julbo Eyewear as well as numerous local companies and organizations.

Ian’s most passionate interests lie in pushing and exploring the limits of his body and mind and exploring the ways others pursue similar transformations. Ian feels at home in the mountains, finding himself always drawn to the alpine and its jagged horizon.


I first tried xact NUTRITION’s energy fruit bars following the 2014 Ultra Trail Harricana and began using during my training and long days in the mountains. – FRUIT2 and FRUIT3 have become a go-to piece of kit for all my athletics: Running, climbing, skiing…everything! What appeals to me is that the bars are phenomenally compact, lightweight, and never result in any sticky or gooey mess; I can carry all I need for a couple of days in a pocket or two. “Tools in all seasons” – I need tools that stand up to the conditions in all seasons. This extends past my apparel, footwear, and hard gear to include my nutrition. xact NUTRITION’s FRUIT2 bars have the best cold-tolerance of any product I have tried and do not melt in hot temperatures. Furthermore, I find the flavours, texture, and composition of the FRUIT2 and FRUIT3 bars to be thoroughly palatable and delicious even after a full day of hard work in the hills.
