The holiday season is a sneaky one.
It’s dark, it’s cold, the calendar fills up faster than your sink does, and if you’re a parent, there’s the beautiful, chaotic swirl of holiday traditions, sugar highs, sugar crashes, and no one knowing what day it is. But winter can also be the season that quietly rebuilds you. It can replenish you, ground you, and set you up for the adventures waiting on the other side of the holidays.
If you’re someone who loves endurance sports (like me)—running, biking, paddling, skiing—this time of year isn’t about crushing mileage or chasing PRs. It’s about creating a foundation that gets you through the holidays feeling strong, steady, and still connected to your body… not overwhelmed by everything else happening around you.
And here’s the part I didn’t expect after becoming a mom: my fitness actually improved, even though my training time shrank. Before kids, when I had endless hours, I’d spend long training days drifting through miles without real intention. Fun, yes, very. Productive? Not always. Once motherhood arrived, I had to strip it all down to what actually worked. I no longer had time to overtrain and honestly, that was a gift.
Endurance athletes are notorious for pushing too hard when life speeds up, and the holidays are basically an all-you-can-eat buffet of stress, joy, logistics, and fatigue. This is not the season to white-knuckle your way through training. It’s the season to support your body, simplify your routines, and stay consistent in a way that feels good.
So below, I’m sharing my six simple winter training strategies to help get us through the holidays feeling strong, grounded, and nowhere near burnout.
Forget monster workouts. Winter is the time for:
If you only have 30-45 minutes, it counts.
If it’s an easy jog around the neighborhood with your kids on scooters, it counts.
If it’s a strength session in your living room while dinner cooks, it counts.
Winter base isn’t sexy. It’s steady.
If life gets wild (because… kids +holidays OR work holiday functions), aim for just four key sessions a week:
Everything else is optional bonus credit.
This system keeps forward momentum without the guilt and I find these four workouts are super easy to stick to. And then if you are able to do anything extra, it gives you an added boost of success and internal high fives.
Intensity is an energetic tax.
In winter, that tax should stay LOW.
Sprinkle in short pickups if you crave speed and if it will help you get out some much needed stored energy, but don’t build your winter around intervals. Save the spicy stuff for after the holidays.
Winter is when recovery actually matters:
This is how you stay strong for months. My Go To's for these are 4 Hour Fuel for my one longer base workout, Gnarly Protein + Collagen for post workouts and Movement Vault for my daily mobility routine.
Kids want to sled? Great—carry the sled back up for your “hills.”
They want to build a snow fort? Cool—that’s your functional strength.
They want a cozy morning? Amazing read and craft with them and run later, or count it as recovery.
Winter base training thrives when your life and your training aren’t fighting each other.
You won’t see huge fitness spikes in the holiday season.
But if you do it right, you’ll feel grounded, you'll feel prepared and when the first of the year hits
—you’ll take off like a rocket.
Base season for Mama's is about playing the long game. And the long game always wins.
We debated long and hard about keeping this secret for ourselves as athletes, but the only thing that is more rewarding than being on the podium at an ultra-distance event, is helping others get to their personal podium! Over the past three years, we've had such success with this formula and fueling paradigm. It has been an integral part of the team's success at our wins of the Patagonian Expedition Race, Expedition Canada, Everglades Challenge, WA360 paddle race, and Chesley's Solo 24 national title. The longer the race (or stage), and the higher output we want/need to maintain - the more crucial it has become.
Energy uptake is key for a great performance in sport over 3 hours. After 15 years with long distance endurance sport I have gotten tired of food during races. But energy that you can drink is easy to consume and get you going.
I always divide my food in 3 groups: high density energy, motivational stuff and funfood. This 4-hour Fuel counts as all 3 at the same time.
24-hour races are all about efficiency if you want to be competitive. In the 2021 USARA nationals, we used 4-hour fuel as 90% of our calories. We never got sick of it and felt powerful on every stage. My team's race plan now includes 4-hour Fuel!
My name is Mateo and I am an ultra endurance bike pack racer based in Bend, Oregon. I have been using your product now for a few months and cannot praise it enough. With the rigors of training, travel and racing, your product is honestly the best supplemental calories in a mixable form that I have ever found.
Daniel Staudigel
fuel designer
Team Bend Racing's Daniel Staudigel developed the initial iteration of 4-Hour Fuel after after his spectacular bonk was filmed for all to see in Amazon's "World's Toughest Race: Eco Challenge Fiji". He needed a more efficient and easy tasting fueling solution for his expedition racing. Since that inception, Team Bend Racing has used the 4-hour fuel across the globe on their way to podium placements in expedition races, 24 hour solo mountain bike events, FKTs, and ultra distance paddling races. Now it is your turn to try it.
How to mix:
Front Country Option (at home) - fill your bottle of choice 2/3 with water (we use a standard 16 or 20 oz bike bottle). Pour that water into a blender, toss in the entire powder packet and blend. Dump into your bottle, and top it off with water. Shake. Go get after it.
For long races that are not super hot, we pre-mix most bottles this way, and leave them in TA bins for up to 60ish hours and have had no problems.
Backcountry mixing (In the TA) - Fill bottle half full with water, then add half the powder and shake like crazy. Add a bit more water and the rest of the powder and shake again. Top off with water and shake as you leave the TA on the way to greatness.
Mixing notes:
It is fine to mix the 4-hr fuel at less than full strength (we recommend at least 1/2 the pack, and then - Congrats, you just made 2-hour tea!), but if you are mixing just 1/4 serving in a bottle (200 cal) - well there are heaps of products out there that do that same thing and will likely taste better at that dilution. We've mixed this formula at all strengths from 2-6 hours in a single bottle and consensus is that the 4-hour strength is the best taste/nutrition/weight ratio for us. Remember, this is high density caloric fuel! That bottle is supposed to last you for 4 HOURS. So it is not your primary hydration source. Carry a separate bottle or bladder with good old straight water. Yum.
Product Concept - we are firm believers in simplicity and science, and yet our experience in expedition racing has often put us into physical and emotional places that are very under-researched. There is plenty out there on how to fuel for a marathon, or a Ironman....but what about when you have to carry all your food?!? No aid stations. Unfathomable distance. And then we add sleep deprivation which just makes everything (fueling included) so much harder.
For our team - this product solves many problems. It eliminates choice. Having a singular primary and palatable fuel source takes the "choice" aspect away from where we get our calories. We know we are getting a "race proven" mix of easy to digest complex carbs, plant based protein, extra BCAAs, electrolytes, and natural fruit sugars.Liquid food is much easier to digest in many race situations, allowing for endurance racers to maintain a competitive output. Bike bottles are convenient and fast to drink from, making it easy to stay fueled on the legs (bike and paddle) that generally have athletes having to choose between slowing down to eat or digging a deep caloric hole as they try to maintain speed and efficiency.
Have questions? Of course you do. Fire away. You can email us at bendracingor@gmail.com or reach out to Jason Magness or Daniel Staudigel or Bend Racing on FB and we are happy to talk. If you wanna tag us in your adventures - we might as well start using #4hourfuel. Thanks so so much everyone.
