Energy gels & race nutrition

Somewhere around 90 minutes into a hard effort, your body runs out of easily accessible carbohydrate and starts negotiating. Runners call this the bonk, and it does not care how fit you are or how good your taper was. One minute you are cruising, the next you are doing math about how far away the finish is and losing. Race nutrition exists to keep that conversation from ever starting.

The framework is simpler than the gel aisle makes it look. For anything under an hour, water is usually fine. Beyond that, most runners aim for something in the range of one gel (or equivalent) every 30 to 45 minutes, starting earlier than feels necessary, because by the time you feel like you need fuel you are already behind. The two rules that actually matter: practice your fueling on long runs until your stomach stops complaining, and never, ever try something new on race day. The porta-potty lines at kilometre 28 are full of people who ignored rule two.

This list covers the main food groups of race fuel: gels, chews, drink mixes, electrolytes, and a few real-food options for people whose stomachs have opinions about maltodextrin goo. Everything here is a known quantity that you can find on amazon.ca without a scavenger hunt. Price bands are relative within the category, not a review score. Buy a few singles, test them on a long run, and figure out what your gut will tolerate at race pace, because that is the only review that counts.

THE DEFAULT

GU Energy Gel

$$

The gel everyone starts with and half the field still uses at kilometre 35. Thick, sweet, and available in more flavours than anyone asked for, some with caffeine and some without. If you have ever picked up a gel at a Canadian race expo, it was probably one of these.

Best for: runners who want the proven, boring, everywhere option

THE FANCY ONE

Maurten Gel 100

$$$

The hydrogel that elite marathoners made famous, with a texture closer to unflavoured Jell-O than syrup. There is basically no taste, which sounds like a flaw until you are 30K in and the thought of another fruit-punch gel makes you gag. You pay a premium for the minimalism.

Best for: runners chasing a PB who have decided their stomach is worth the money

NO WATER NEEDED

SIS GO Isotonic Energy Gel

$$

Noticeably thinner and larger than a standard gel, designed to be taken without chasing it with water. That makes it handy between aid stations, though the bigger packet takes a few extra seconds to get down. A long-time favourite of triathletes, who love nothing more than eating while moving.

Best for: runners who hate timing their gels around water stations

TASTES LIKE FOOD

Honey Stinger Organic Energy Gel

$$

Honey-based, so it tastes like something that exists in nature rather than a lab. The texture is classic honey, which means it can get thick in cold weather, worth knowing for those March races where the start line is minus five. A good gateway gel for people suspicious of the whole category.

Best for: runners who want their fuel to taste like actual food

PRE-RACE BREAKFAST

Honey Stinger Waffle

$$

A stroopwafel with a sports nutrition label, and honestly one of the better snacks in running. Too crumbly and chewy to eat at race pace for most people, but excellent an hour before the gun or on an easy long run. Also dangerous to keep in the pantry, because they disappear.

Best for: the pre-race window and long slow days, not mid-race fueling

FOR GEL HATERS

Clif Bloks Energy Chews

$

Big gummy cubes you can portion out instead of committing to a whole gel at once, which is nice when your stomach is on the fence. The margarita flavour has extra sodium and a cult following. Downside: chewing at threshold pace is a skill, and the cubes firm up in the cold.

Best for: runners who would rather chew their carbs than shoot them

SUBTLE FLAVOUR

Skratch Labs Sport Hydration Drink Mix

$$

A drink mix that tastes lightly of real fruit instead of neon sports-drink concentrate, with sodium and a modest amount of carbohydrate. It is deliberately not a full meal in a bottle, more of a hydration base you fuel alongside. The lemon lime is the safe pick.

Best for: runners who find regular sports drinks aggressively sweet

ALL-IN-ONE BOTTLE

Tailwind Endurance Fuel

$$

The opposite philosophy from Skratch: put all your calories and electrolytes in the bottle and skip solid fuel entirely. Popular with ultrarunners and anyone whose stomach rejects gels outright, since sipping steadily is gentler than a gel bolus. Requires actually drinking on schedule, which is harder than it sounds.

Best for: long-haul runners who want to drink their calories and be done with it

THE SALT SHAKER

SaltStick Caps

$$

Electrolyte capsules that many runners use to top up sodium on hot days or long efforts when sweat losses outpace what their drink covers. Tiny, flavourless, easy to carry in a pill flask. Not fuel, just minerals, so they complement gels rather than replace them.

Best for: heavy sweaters and hot-weather racers dialing in sodium

THE CANADIAN ONE

Xact Energy Fruit Bar

$

A small chewy fruit bar from a Quebec company, roughly gel-sized in carbs but in food form. It goes down easier than a bar and does not require the commitment of goo, and there is something satisfying about fueling a Canadian race with Canadian fuel. Common sight at races in Ontario and Quebec.

Best for: runners who want real-food fueling without eating a full granola bar

Check it on Amazon.ca →

EVERYDAY HYDRATION

Nuun Sport Electrolyte Tablets

$

Fizzy tablets you drop in a bottle for electrolytes with barely any calories, so this is hydration support rather than fuel. Great for hot training days, travel, and the day before a race when you are drinking more water than usual. The tube format survives a gym bag indefinitely.

Best for: day-to-day hydration and pre-race prep, not race-day calories

Worth knowing

  • Practice your exact race fueling on long runs, same brand, same timing, same flavour, so race day contains zero experiments.
  • If you use caffeinated gels, save them for the back half of the race, and check the label, because caffeine content varies a lot between flavours of the same brand.
  • Buy singles or a variety pack before committing to a case of 24, because a case of a flavour you hate is a very long-term relationship.
  • Canadian road race aid stations most often stock water and a sports drink like Gatorade or Nuun, and sometimes gels at bigger marathons, but carry your own if your plan depends on a specific product.
