How to Fuel Ultra-Distances: The World’s Toughest Mudder

ScreenShot2012 06 14at40753PMA couple weeks ago, I received an enthusiastic email from a group of Aussies. They were planning on competing in the World’s Toughest Mudder (WTM), a perversely-warped, extreme version of the regular Tough Mudder that has contestants complete as many 8-10 mile circuits as they can in a single 24-hour period. To get the spot in the WTM, their four-man team had to place in the top 5% of finishers in the Melbourne Tough Mudder, so they aren’t physical slouches by any means. They’re also Crossfitters, rugby players, and avid Primal eaters. Simply put, these guys make us real proud.

They weren’t writing just to say “hi,” however. They also needed Primal fueling advice, especially since the guy who won last year’s WTM ate anything but Primally. For a single, one-time, all-out event, I’d actually say that making concessions with your diet are fine, but these guys weren’t having it. They wanted to stay Primal for the duration and avoid all the sugary gels and extruded pasta in a vacuum bag (yes, people are really eating this).

ScreenShot2012 06 14at41903PM

Did I already say they make us proud?

Well, is such a thing even possible? And if so, how would you go about doing it?

Let’s read the relevant portion of their email before we begin:

Hi Mark,

On the 31st of March 2012, myself and a team of mates competed in Australasia’s first ever Tough Mudder race on Phillip Island in Melbourne, Australia. Tough Mudder is a 20km obstacle course race designed by British Special Forces which tests endurance, strength, mental commitment and teamwork and is one of around 30 events held annually across the globe.

Out of the 26,000 entrants in the Melbourne event, my team and I managed to finish in the top 5% of all finishers and subsequently have been selected to go to the world championships in Englishtown, New Jersey, USA. The world championships puts the world’s most hardcore Mudders through a grueling 24-hour challenge designed to find the toughest team on the planet. When the mud settles on November 18th, 2012, a select few winners will have bested 500,000 others worldwide for the right to call themselves the World’s Toughest Mudders.

Like any good team about to undergo a huge challenge we have been researching the event and preparing mentally and physically. As Primal eaters we are obviously interested in diet. Last week we found the winning athletes’ diet (Junyong Pak) from 2011 below is his advice and Race Diet plan (I think this much sugar could kill all 4 of us!)

‘In addition to Powerbar gels, I decided to supplement with canned fruit in heavy syrup, pasta, PB&J, protein drink, gatorade, honey, eggs, and bananas. I forgot to eat the honey, and did not make eggs or bring bananas but ate everything else. The canned fruit (peach chunks, halved pears) was a huge winner. I packaged these into vacuum seal bags such that each bag contained half a can of fruit, or 175 calories. These were robust bags that did not break, relatively compact, and also supplied some of my water intake. I could bite off a corner of the bag without taking my gloves off and bite the fruit out like a gel. I packaged the pasta in similar fashion with much success.’

Mark, as you can see, I think if we did this we would all be in a sugar coma and never wake up. Can you help us come up with something Primal to fuel us through the race?

4 Man Team:
James Laird: 28 yrs, 6’2″, 95kg
Scott Laird: 25 yrs, 6’1″, 80kg
James Stiles: 28 yrs, 6’2″, 88kg
Marc Burbrough: 25 yrs, 6’4″, 92kg

Thank you and regards,

PRIMAL TOUGH MUDDERS

Here’s a video of the guys in action to give you an idea of what they’re up against:

It’s gonna be like that, only crazier, and performed multiple times across the day.

First of all, hats off to them. If I had to do another ultra endurance event sometime in my life, the World’s Toughest Mudder would probably be high on my list. It looks like good, clean (well, dirty, actually) fun. It may be fun that takes a week to recover from, but fun nonetheless.

Second, the WTM is not just an ultra-endurance event. With some 24 obstacles ranging from sprints up steep muddy hills to climbing towers and vaulting over walls to swimming through ice-water (and plenty of as-yet unannounced obstacles), you’re not just going to chill out in the oxidative energy pathway, burning fat for energy. The bulk of your energy can – and will, if you take the necessary steps – come from fat, but defeating most of those obstacles (over and over again across 24 hours) will also require intermittent forays into the ATP-PC and anaerobic pathway. Your nutrition, then, has to take both aspects of the race into account.

A month or two before the race:

Become a fat-burning beast.

This may not be a stretch for you bunch, seeing as how you’re already following a Primal eating plan. If you are fat-adapted, stay adapted. If you aren’t, get fat-adapted. Being a fat-burning beast will help you efficiently burn all that body fat for energy (and even the lean among us have enough body fat to provide energy for a 24 hour ultra distance event) and hold off on burning glycogen until you really need it. Doubleplusgood. If you aren’t already adapted, I would recommend limiting your daily carb intake to around 60-70 grams in the months leading up to the race. This will train your body to rely on fat for energy while sparing glucose.

Titrate down your Crossfit metcons.

I know, I know – if you’re like most CrossFitters, you get off on the metcon intensity, and you owe a lot of your physical prowess to training that way. But those metcons burn through glycogen like crazy, and if you continue to follow the 3 on, 1 off (or even 2 on, 1 off) workout schedule without upping the carbs, you’re going to burn yourselves out. Keep the metcons to once, maybe twice a week, shorten them up considerably (5-10 minutes instead of 20-30 minutes), and up the intensity while reducing the volume. Make sure to do some simple, basic, low-rep, low-volume, high-intensity, low-stress strength work instead.

A couple days before the race:

Fill those glycogen stores.

But Mark… didn’t you just say to go low-carb to maximize our bodies’ fat-burning and glucose-sparing potential? What gives? Simple. Two days of (healthy Primally sourced) carb loading to the tune of 350 grams or so per day will top off your glycogen stores. Since you’ll be getting your carbs from whole food sources like sweet potatoes, potatoes, squash, fruit of all kinds, and, if you swing that way, rice, you may have to eat what seems like a large amount of food. It’s not, not really. People act like it’s impossible to eat carbs while eating Primal, and I don’t get it. Just reach for the tubers and fruit.

Take it easy.

Don’t CrossFit, don’t lift, don’t do much of anything that will sap your stored energy and exhaust your muscles. Go for a walk, work on mobility, do some yoga, or do nothing at all. Enjoy your (brief) time off!

Race day:

Eat a light breakfast.

Couple strips of bacon, a couple eggs, some fruit, and strong coffee. This will give you a bit of something in your stomach without weighing you down, and the coffee will liberate some fatty acids for use during the event (not that you need help with that).

Eat some medium chain triglycerides (MCTs).

Why MCTs? They can’t be stored, meaning they must be utilized for energy. MCTs also increase the production of ketones. These are good things, since fat is going to be your ticket through this race. In most cases, I’d tell you to get your MCTs from a whole food source, like coconut oil. Not today. Today, I want you to take three tablespoons of pure, unadulterated MCT oil. If the thought of that appalls you, try frothing it up in your coffee.

Drink some salty broth.

Broth, especially homemade broth dosed with plenty of sea salt, provides easily-assimilable electrolytes like sodium, calcium, and magnesium. You’re going to be excreting a lot of sodium, so add 2-4 grams of sodium. Not salt, but sodium. Hey, didn’t I say to drink salty broth? For reference, sea salt is about 1.8 grams sodium per teaspoon, while table salt is about 2.3 grams sodium per teaspoon.

During the race:

Keep a fat source at hand.

MCT oil, nut butter, and coconut oil are squeezable and fat-rich. Maybe toss in some hard-boiled eggs for protein and fat.

Keep a slow-digesting carb source at hand.

Peter Attia, the endurance athlete who’s been training in a ketotic state for months now, recommends Superstarch, a non-GMO cornstarch that provides steady, even glucose. Best of all, Superstarch doesn’t spike insulin, especially when compared to maltodextrin, so you can take it during a race without impacting your ability to burn fat.

If you can’t get your hands on Superstarch, plain cornstarch (not maltodextrin, which is absorbed too quickly and results in too large an insulin spike) will work tolerably well.

Keep an energy drink on hand.

I recommend the molasses/honey/coconut water hybrid mentioned in this post. Consider mixing in more sea salt for sodium, too, as you’ll be excreting tons of that.

That’s what I’ve got. The key to doing this thing in a low-carb state, of course, is that you are completely fat-adapted. Becoming a fat-adapted fat-burning beast will make you or break you. Choose wisely, my friends, and be sure to let us know how you do! Grok on!

You want comments? We got comments:

Imagine you’re George Clooney. Take a moment to admire your grooming and wit. Okay, now imagine someone walks up to you and asks, “What’s your name?” You say, “I’m George Clooney.” Or maybe you say, “I’m the Clooninator!” You don’t say “I’m George of George Clooney Sells Movies Blog” and you certainly don’t say, “I’m Clooney Weight Loss Plan”. So while spam is technically meat, it ain’t anywhere near Primal. Please nickname yourself something your friends would call you.

  1. I thought ultra-distance sports were unhealthy?

    Inus wrote on June 14th, 2012
    • I think it is unhealthy to constantly train for them. This is a bit different because you have to do so much other stuff to really be ready. Running is only a small part of it and you are often waiting at the obstacles so you do get some “rest”.
      Also, I am not sure these events are about being healthy, they are more about pushing yourself to see what you can do. If you train properly you’ll recover pretty quickly.

      spayne wrote on June 14th, 2012
      • Well said. Training hard like you have to for this event long term is not healthy. But, you can recover. And they aren’t doing it to try and be as healthy as possible.

        They want to push themselves to the max!

        Primal Toad wrote on June 14th, 2012
      • Go Guys! Training for a goal – and having a BALL in the process is an excellent objective! Not like they will be doing this all the time and what an achievement! Go Aussie GO!!

        Michelle wrote on June 15th, 2012
    • First of all, 20km is not an ultra distance. It may well be ultra hard to run it, but the distance does not quualify as ultra. If you want to race for 20km (or 42km for that matter) and train for this then you need to push quite hard for quite a while. It is unhealthy. It is a bit different with ultra runs (>42km). Unless you truly want to compete, you will just want to finish and will take it easy. You will also have to pay more attention to quality nutrition and stress management. You will have to perfect your running style. You will have to learn to listen to your body, stay mindful. You will have to train your body to burn fat for fuel. You will probably run on trail rather than concrete. All of these are good things! Paradoxically, running an ultra, every now and then, can be healthier than training for and runningh multiple marathons per year.

      Martin wrote on June 15th, 2012
      • you’re right, 20k is not an ultra distance, however, it says in the opening section that their objective in this is to complete ‘as many’ of these 8-10 mile cicuits as they can. So, a little simple multiplying will quickly get them into the realm of ultras.

  4. I just completed the Tough Mudder at Beaver Creek, CO. I am not going to say these guys have it easy but add about 11,000 feet of elevation and man, it adds a whole other element to the event.

    Anyway, awesome post. These guys kick ass. I was out there for almost 5 hours, I can’t imagine 24.

  7. I want to recommend macadamia nuts as well, for the weight they are the best fat with a bit of protein that you can carry in your pack. Antarctic explorers have found them to be their perfect fuel, though they eat the chocolate covered ones… No fear of melting.

    Christa wrote on June 14th, 2012
    • Ooooh, macadamia nuts covered in super dark chocolate. That would be great to take on the 10 day high altitude backpacking trip that I am training for.

      PhilmontScott wrote on June 14th, 2012
  8. I love sweet potatoes. But, I find that they spoil too damn quickly. Even when the best-by date is not for 4/5 days after purchase, I have found that they can be spoiled once i cut them open. I know how to inspect for good sweet potatoes, but sometimes it’s only when you slice them that the truth is revealed. If can avail of good sweet potatoes, consider yourself lucky.

    I have a nutritionist friend who works with athletes and even prepares some of there meals. He has access to a Whole Foods and he never encounters spoiled potatoes, unless of course food is not used.

    Brad wrote on June 14th, 2012
    • Sweet Potatoes shouldn’t spoil quickly, are you keeping them in the fridge or something? If you keep them in a cool dark place they should keep as long as white potatoes.

      Sandra from NZ wrote on June 15th, 2012
    • Hummmmm…not sure where you live or what you’re doing wrong? I keep my cut sweet potatoes in the fridge and they usually last 2 weeks! I can also put them in “fresh & Crisp” storage bags for lasting longer. Uncut ones I keep in a dark place in a cupboard. No problems, last for 2 MONTHS!!

      Marc B wrote on June 14th, 2012
  10. What blows my mind about these top athletes’ diet is the utter lack of nutrients. Our bodies require so much nutrients to make shit happen. I mean, they need vitamin C for protein synthesis, which is going to be pretty important as they’re breaking down muscle constantly. They need b-vitamins and electrolytes. Magnesium gets used up pretty quickly in times of stress and inflammation will need to be calmed with anti-oxidants.

    Anyway, it’s just not all about calories is it?

    Props to you, Mark, for advising they drink bone broth!

    Peggy The Primal Parent wrote on June 14th, 2012
    • I whole-heartedly agree! I was just thinking this exact same thing today while preparing my post workout meal.

      To bulk up you need calories. You need protein and carbs. You need fat too.

      You also need vitamins and minerals. If you passed on these then you would miserably fail.

      No wonder REAL FOOD works so well?

      Primal Toad wrote on June 14th, 2012
    • Good call Peggy!

      Athletes tend to think of “What fuel do I need to have a good performance?” and forget to ask “What micronutrients does my body need to make use of this fuel safely and effectively?”

      Jeffrey of Troy wrote on June 14th, 2012
    • Excellent point–some of the most processed, nutrient-bereft garbage diets I’ve seen are consumed by endurance athletes. There is such a focus on numbers in these events, I think all they see is fuel in fuel out. I also think there is a bit of elitism, fueled by clever marketing by the producers of supplements (“what? Your race fuel is food? Aren’t you going to supplement? How naive…”)

    • There is just the thing you’re looking for. It’s called Warrior Dash. Only 5K, but obstacles to overcome like Tough Mudder. Just a mini version…

      It’s usually held in conjunction with Tough Mudder, so should be easy to find one.

    • Completely agree! Taking MCT oil can make even us fat adapted folks nauseous when you start taking it all of a sudden. I totally recommend taking a little bit in the beginning-like MONTHS before race day and slowly upping your dose over time. I made the mistake of putting an entire TB in my morning coffee the first time I tried it and THEN performing a HIIT. Uuuhh, yeah, big mistake.

  23. One of the race directors (& an exercise physiologist) at the recent PCT 100-mile event gave a strong recommendation for ‘Succeed’ brand electrolyte caps (versus all the usual electrolyte drinks available at the aid stations), based on his personal and race experience. They incorporate much of their sodium in the form of sodium bicarbonate. IFIRC, this guy’s magic formula was 1 capsule with every bottle of water (16-24 oz?); worked wonders to prevent hyponatremia, especially after about 30 miles on hot days. If true, then your recommendations for high salt are right on, for these real long races.

    All the usual disclaimers, etc.

  33. Hey Mark,
    I don’t want to sound challenging or accosting (I’m a big fan of Primal eating and your work), but how come you don’t use Superstarch in your supplements (I’m not sure how many of your supplements use maltodextrin, I was curious since I didn’t know an alternative to maltodextrin was available, though I don’t know how costly it is)? I don’t know if maltodextrin works better when making supplements (and I get we should really be eating whole foods and relying mainly on supplements like Omega-3s, etc.) but it was just a thought I had. Is it practical to make supplements that have all-Primal ingredients?
    Thanks, and love your work!

  35. This article is so helpful! I am just about to compete in the Sydney competition in september with four of my girlfriends. We are all 20 or 21 and very into fitness, but are doing this more for ‘fun’ than anything else. It’s great to have these diet tips. You read so many other pre-comp plans, but considering I’m coeliac and try to stick to mainly a paleo diet (with dairy sometimes) they’re all very unhelpful. Thanks Mark!

  37. Not to be antagonistic, but one common argument is that carbs are the best source of fuel for ultra-distances.

    Proponents of this belief will say that most successful ultra-marathoners follow a high carb low fat diet.

  39. Great stuff lads!
    I’m also primal and I’ve not long completed a 170 mile bike ride, road/tracks over two days, maybe not as extreme as your event, but i survived on water, bananas and pitted dates filled with coconut butter, i put 4 dates in bags for convenience and just had my usual primal breakfast and evening meal. Good luck!

    • Cheers Dave, Those dates sound awesome!

  40. Excellent article!! One additional question to follow up the recommendations… How would the “recovery” phase be?
