Winter within the Northern Hemisphere is in full impact, with snow falling and our runs turning into slushy shuffles. Our winter seasons are sometimes stuffed with lofty targets for the months forward, however the quick days and chilly climate don’t assist with our motivation to get outdoors and run.
On this article, we’ll discover the info to see what the winter months seem like within the ultrarunning world. We’ll then dive into some data-based coaching approaches for tackling the winter season successfully.

Ultramarathon Racing within the Winter Season
To know what the operating panorama seems to be like throughout the winter months, let’s flip to the numbers. For this primary evaluation, we use knowledge from the DUV Extremely Marathon Statistics database for U.S. races. The dataset we deal with is ultramarathon races in the USA from 2022 to 2024, with a minimum of 10 members. This primary view reveals the variety of races by season.

Breaking this down month-to-month, we are able to see a extra detailed view.

The winter season within the U.S. begins in December and continues into January and February. The variety of races will increase within the spring months, with a slight dip headed into the recent summer time months, after which choosing again up within the fall season.
Winter and summer time, in fact, are usually not equal in all states. Winter in Louisiana is a superb time to get outdoors and be lively, however you might wish to wait just a few months for those who reside in Minnesota. I wished to interrupt down these races by geography, to see what the distribution of winter occasions was like by location. The next graph reveals the share of ultramarathons by state that happen within the winter.

Most northern states have lower than 10% of races occurring throughout winter. States with extra average or heat climates see a bigger proportion of races occurring throughout this timeframe. Louisiana was the one state with nearly all of its races going down in winter.
In most areas, winter is the season with the fewest ultrarunning occasions. This quieter time of yr gives a chance to reset and deal with bettering weak areas for the season forward. When you reside in a area that experiences winter, getting outdoors on darkish, chilly evenings is probably going much less interesting. That is one thing I battle with, having lived within the northern half of the USA my total life. With a number of formidable plans for the spring and summer time months, I dove into how one can benefit from this winter.
What We Can Study from Kilian Jornet’s Winter Coaching Information
Searching for inspiration for our winter coaching journeys, we turned to the GOAT, Kilian Jornet. Evaluating your self to him is usually a self-defeating spiral, however there are some useful classes to be discovered from his strategy to the winter months — and a lot knowledge!
After a historic 2022 season, with wins on the Zegama Marathon, Hardrock 100, and UTMB, Jornet revealed a detailed coaching log. The log recounts his 2022 season intimately, and gives the context of all of the years of continuous coaching main as much as that time.

The above chart reveals a fast overview of Jornet’s coaching knowledge going again to 2009. The crimson circle is the 2022 season. The primary takeaway from this chart is that Jornet has been persistently placing in a variety of coaching quantity yr after yr, main as much as his wonderful performances in 2022. He notes that wanting on the crimson circle in isolation is ineffective with out the context of earlier years of coaching and diversifications.

The a part of this graph that caught out to me is the repetition of blue bars each winter the place his coaching turns primarily to ski mountaineering. Let’s deal with these ski mountaineering periods that Jornet does throughout his winter block. Jornet lives in a chilly winter local weather in Norway, and the coaching throughout these months is tailored to the circumstances. His winter block in 2022 went from December to the tip of March, with most of his coaching being ski mountaineering in coronary heart fee zone 2. These outings often lasted two to 4 hours, typically adopted by treadmill operating within the night. See a zoomed-in model of what this seems to be like.
A zoomed in model of the above chart reveals the breakdown of Kilian Jornet’s 2022 coaching, together with a winter block which was primarily ski mountaineering.
With the primary coaching being shifted to lengthy ski mountaineering periods, the operating quantity is considerably lower down. It is usually fascinating to notice that Jornet doesn’t do “any depth besides a few [ski mountaineering] races” throughout this era. That is proven within the graph beneath, with no marks on the velocity, tempo, or threshold periods that he breaks down in his submit, till later within the yr when he enters a extra targeted coaching block.

Jornet stored his depth low all through winter, and his coaching targeted on constructing a powerful cardio base. This cardio base got here primarily within the type of ski mountaineering, with operating quantity fairly low for an athlete at his stage. Throughout the 2022 winter block, Jornet averaged a modest 53 kilometers (33 miles) of operating per week, which is boosted by the outlier of a 100-mile race completed throughout this time, to check fueling. Under I’ve damaged out a graph to point out this operating quantity throughout this winter block.

Throughout the remainder of the yr, Jornet’s weekly mileage was stored round 150 to 190k (93 to 118 miles). This discount in operating mileage throughout the winter months permits him to construct an ideal cardio base by way of lower-impact ski mountaineering periods. A powerful cardio base results in numerous diversifications, which improve the effectivity of muscle fibers and enhance one’s time to fatigue.
It’s unattainable to be Kilian Jornet, and I’m certain many readers don’t reside close to massive mountains in Norway, and can’t dedicate 4 hours per day to coaching. Whereas your winter coaching will seemingly not seem like this, this detailed breakdown of coaching knowledge gives mannequin for framing the yr forward.
Winter is a superb time to set the foundational health for the remainder of the season. Structuring a winter block to cross practice or enhance weak areas can set you up for fulfillment in later seasons. The kind of winter coaching may fluctuate, relying on the place you reside and what actions you take pleasure in. It may very well be backcountry snowboarding, competing within the Tour Du Zwift, or Netflix and the treadmill.

A number of fascinating research help a cross-training strategy between aggressive seasons. This research examines the results of substituting 50% of feminine distance athletes’ run coaching quantity with biking. The outcomes present that cross coaching maintained cardio efficiency in comparison with operating. One other research evaluating 4 weeks of outside elliptical bike coaching to operating coaching yielded related outcomes when it comes to efficiency upkeep.
Cross coaching might be a good way to remain motivated and proceed coaching throughout the winter. Searching for some concepts to get you began? Try this information to cross coaching.
On the finish of the day, the messages within the knowledge are these: With fewer races within the winter months, we might wish to flip to different coaching modalities to move the season. Doing what you take pleasure in and is long-term sustainable will let you proceed stacking bricks yr over yr. And whereas we might not stack as many bricks of ski mountaineering or operating as Kilian Jornet, staying lively within the winter months and constructing a powerful cardio base will set us up for race-specific coaching and races themselves later within the yr.
