Day three of a canoe trip: the food pack is lighter, the pot of rice and beans is the best thing anyone has ever eaten, and the bag of trail mix keeps going around the fire. Meanwhile, a C2 sprint crew eats lunch between morning and afternoon water sessions at a training camp, a slalom C1 teenager has a banana between runs, and a marathon pair mixes bottles for a crew to hand over at the next bridge. Canoeists eat in very different places, but the basics are the same: enough food for the work, enough carbohydrate to fuel it, protein to rebuild, water you can trust, and very few supplements. Here is the short, honest version for every level.

General information, not medical or nutrition advice. Talk to a doctor or registered sports dietitian before changing your diet or starting a supplement. Back to the canoeing hub.

How much do canoeists need to eat?

It depends on how long and how hard you paddle, and whether you carry the boat. The Compendium of Physical Activities rates canoeing on a camping trip at 4.0 METs, moderate canoeing at 4–6 mph at 5.8, portaging at 7.0 and competitive canoeing over 6 mph at 12.5. Guidelines from the American College of Sports Medicine (ACSM) and partner dietitian groups scale daily carbohydrate with training load:

Training load	Carbohydrate per kg per day	For a 70 kg canoeist
Light (easy paddles, skill sessions)	3–5 g	210–350 g
Moderate (about 1 hour of exercise a day)	5–7 g	350–490 g
High (1–3 hours of hard training a day; long trip days)	6–10 g	420–700 g
Very high (4–5 hours a day; marathon camps, big portage days)	8–12 g	560–840 g

Protein: about 1.2–2.0 g per kg of body weight a day, spread across meals, with 15–25 g after training. Most canoeists who eat three real meals and pack snacks get there without powders. What to eat on the water itself is on canoe trip and race day.

Sprint, slalom, marathon and tripping canoeists

• Sprint and slalom racers (C1, C2, C4): a review of nutrition for power sports, canoeing and kayaking included, stresses enough total energy for high training volumes, plenty of daily carbohydrate (low muscle glycogen hurts high-intensity performance), well-timed protein, and fast refueling between heats. Power-to-weight matters, but changes in body composition should be slow and supervised.
• Marathon and downriver racers: races like the 70-mile General Clinton Regatta or the 120-mile, overnight AuSable River Canoe Marathon are won and lost on fueling. An open canoe makes food easier to reach than in a kayak, but you still need a schedule: eat and drink every 30–45 minutes in training with the products you’ll race with, and practice crew hand-offs.
• Trippers: portages turn food weight into work, so pack calorie-dense foods that keep (oats, tortillas, pasta and rice, nuts and nut butters, hard cheese, dried fruit, bars), in waterproof packs or barrels you can carry. Plan a real hot dinner and an extra day of food in case wind keeps you on shore. Losing weight steadily over a long trip is a sign to eat more.
• Weekend and family paddlers: normal healthy eating covers it. Bring water and a snack for anything over an hour, and more for kids, who get cold and hungry fast.

Water on a canoe trip

Lakes look clean, but don’t drink untreated water: in a survey of whitewater paddlers, 14% reported having had giardia. Filter or treat what you drink, carry a wide-mouth bottle like the Nalgene Sustain 32 oz where you can reach it, and drink to thirst through the day, a bit more in heat and on portage days. Electrolyte mixes help on long, sweaty days; if you have high blood pressure, kidney or heart problems or follow a low-sodium diet, ask your doctor first.

Eating enough: REDs

The International Olympic Committee’s 2023 consensus statement on REDs (relative energy deficiency in sport) warns that eating too little for your training affects both women and men: bone health, hormones, mood, illness and performance. Paddling squads aren’t immune: when the women of the Polish national kayak team were screened, about 15% (5 of 33) had menstrual cycle problems. And in a survey of elite teenage flatwater paddlers, female canoeists had a higher injury rate than male canoeists, one more reason to make sure young athletes are fueled. Warning signs include constant tiredness, frequent illness, stress fractures and, in women, missed periods. Restoring energy intake is the main treatment, with a doctor and dietitian involved. Young canoeists shouldn’t diet to make a crew or hit a weight.

Supplements: what the evidence says

The IOC’s 2018 consensus statement on dietary supplements comes down to “food first”: a few products have good evidence for some athletes, and most add little.

• Sports drinks, gels and electrolytes: useful sports foods for long or hot days and marathons.
• Protein powder: a convenience after training or on a trip when real food is hours away; not needed if you eat well.
• Caffeine, for adults: one of the better-studied performance supplements. In a 2025 double-blind trial with 20 highly trained male canoe sprint athletes, caffeine improved a 500 m ergometer time trial by about 1.9 seconds compared with a placebo; theacrine, a related compound, did not on its own. Caffeine can cause anxiety, an upset stomach, poor sleep and a racing heart, and it isn’t for everyone (heart conditions, pregnancy, sensitivity). Stay within the label.
• Creatine, for adults: among the most studied supplements; many sprint athletes use it for strength training. It can add a little body weight.
• Vitamin D and iron: test, don’t guess. Extra iron you don’t need can do harm; get blood work through your doctor first.
• Young canoeists: the American Academy of Pediatrics says caffeinated energy drinks have no place in children’s and teens’ diets and advises against creatine for young athletes.

Third-party testing

Canoe sprint and slalom are Olympic events (at LA28: men’s C1 1000 m and C2 500 m, women’s C1 200 m and C2 500 m, and C1 slalom for men and women), and national-team canoeists can be drug-tested. Under anti-doping “strict liability” rules, a contaminated supplement is no excuse. One international study found about 15% of 634 supplements contained undeclared prohormones. Programs like NSF Certified for Sport and Informed Sport test products for banned substances. They lower the risk without removing it, and they don’t test whether a product works.

Product	In one serving	Certification	About (Oct 2026)	Per serving
Thorne Whey Protein Isolate	21 g protein	NSF Certified for Sport	$65 / 30 scoops	about $2.17

Why these: the Thorne and Klean products are NSF Certified for Sport, GU Energy Gel is listed as Informed Choice, Nuun says its Sport tablets are Informed Choice certified, and Skratch’s maker says it is NSF Certified for Sport (we couldn’t find it in NSF’s search, so look it up before relying on it). Some GU flavors contain caffeine; check the label. Follow the label for how much to take. Full comparisons: best protein powder for athletes, best electrolyte powders, best energy gels, best creatine and best multivitamin for athletes.

Talk to a professional. Before starting any supplement, check with your doctor or a registered sports dietitian, especially for canoeists under 18 and anyone who is pregnant, takes medication or has a heart, kidney or other medical condition.

Keep going with canoe training and canoe recovery. Kayakers face the same basics with less room to reach their food: kayaking nutrition.

Canoeing nutrition: FAQs

How many calories does canoeing burn?

It depends on your size, speed and the conditions. The Compendium of Physical Activities rates canoeing for pleasure at 3.5 METs, moderate canoeing at 5.8, portaging at 7.0 and racing over 6 mph at 12.5, so a hard session or a portage-heavy day burns several times an easy float.

What food should I pack for a canoe trip?

Calorie-dense foods that keep and carry well over portages: oats, tortillas, pasta and rice, nuts and nut butters, hard cheese, dried fruit and bars, in waterproof packs. Plan a hot dinner each night, snacks in a thwart bag, an extra day of food for wind days, and a way to filter or treat water.

Do canoeists need protein powder?

Most don’t. Guidelines suggest about 1.2–2.0 g of protein per kg of body weight a day, which regular meals usually cover. A shake is a convenience when food is hours away; choose a third-party tested one if you could be drug-tested.

Does caffeine help canoe racers?

In a 2025 trial with highly trained canoe sprint athletes, caffeine improved a 500 m ergometer time trial by about 1.9 seconds. It isn’t for everyone (heart conditions, pregnancy, sensitivity), it can upset sleep and stomachs, and the AAP says teens should skip caffeinated energy drinks. Try it in training, never first on race day.
