Eastern Canada, home of XACT in Montréal, QC, is prone to some pretty harsh cold snaps in the winter. Temperatures can easily dip to -25C (-40C with wind chill) but it is by no means a reason to not get outside and enjoy your favourite endurance sport.
For many, winter running itself is the challenge to be conquered, and for others who are signed up for a Spring marathon, training in the winter is a must. And just like any time of the year, fuelling those long runs is the key to success and having fun!
Stick to your regular nutrition plan. You will burn only a few more calories due to heat loss in the cold. Shivering does burn many more calories, but hopefully you are dressed for the task!
Avoid ‘freezing’ foods! Many granola bars and gels hardened up in the cold weather. Right to the point where chewing will be a workout in itself. FRUIT2 and FRUIT3 have been tested all over the world including the Candian Arctic by our very own Ray Zahab and Jen Segger. Even in these crasy temperatures they keep their softness. The FRUIT2 bars that is .. Ray and Jen are abviously as hard as nails .. never soft!
Keep your fingers warm. Opening gels and bars is next to impossible if you are one of those who gets ice white fingers that go numb (also known as Raynaud’s disease). If you can keep your hands warm you can more easily open your gels / chews.. and maybe more importantly, that zip pocket where you stashed your house keys!
Change your gel / chew pocket. Rather than using your jacket pocket, your mid-layer or leggings may have a stash pocket that will be slightly warmer! Just think about ease of access versus the need to keep food warm. Pro tip: chocolate doesn’t want to get too warm ;)
Just because you are not sweating like you might in the summer, it doesn’t mean you will not dehydrate. Your intake may be lower but hours on the trails without fluids will affect your performance. Aim for 250-500 ml per hour depending conditions.
Some like it hot! ... their hydration that is! Why not try a hot drink in your flask rather than the usual water. This will give you more time before your bottle freezes and doubles as a nifty hand warmer. Just don’t pour straight from the kettle, give it a moment to cool. Coffee or tea works and add a little sugar for sweetness and extra carbs.
Alternatively, mix in a hydration powder, the sugars and salts will bring down the freezing point of the water.
Some hydration gear manufacturers offer insulated bottles. This can be handy for keeping drinks cool in the summer too!

Protein is an essential part of the diet, but I find there still are a lot of misconceptions about its role in sports nutrition. How many times have you heard you need to get your protein in immediately after a workout?
Alister Gardner made a promise to never complain about the heat in the summer, but to embrace it fully, he had to learn how to hydrate properly. In his latest article, you will learn more about hydration during endurance events.
The subject of ultra-endurance nutrition is tricky and opinions are very divided. However, the scientific literature on this topic is quite abundant and the recommendations are clear. Learn more about that in David Jeker latest article.
