Read Emily Sisson's marathon fuel plan before you write your own. She is a two-time U.S. Olympian who competed at the 2024 Olympic Marathon in Paris, and she set the American marathon record in 2022, running 2:18:29 in Chicago as the first American across the line in the women's race. Her plan is unusual for one reason: she drinks her race fuel.
This is the plan she published with UCAN, reproduced as written, converted to kilometres, with notes on how to run it with the range stocked in Victoria. The recovery half gets as much space as the racing half, because that is where her plan is most different from most runners'.

Three things in her plan worth copying
Fuel on the clock, not on feel
One serving of Energy Powder in water every 10 km of the marathon. Every 6.5 km on long runs.
Recovery starts at the line
A Cocoa Energy + Protein shake with oat milk straight after finishing. The meal comes later.
The week before is part of the plan
Energy Powder and Hydrate on the nights leading in, 8+ hours of sleep, less fibre, less phone.
Contents
Nothing in Emily Sisson's plan depends on running 3:17 per kilometre. The breakfast is toast and coffee. The race fuel is a powder in water, taken at the same four points a 4-hour runner passes. The recovery shake takes two minutes. What separates it from the average age-grouper's plan is not the products, it is that every step has a time attached and none of it is improvised on the morning.
The other reason it travels well is the drink format. In Australian conditions, a humid Gold Coast start or a Melbourne morning that warms up fast, carrying your carbohydrate in the bottle solves fuel and fluid in one action. Her plan maps directly onto the UCAN marathon fuel plan; the products she names are the products on this site.
The night before
Carbohydrate with lean protein
Rice or pasta with chicken or salmon. She cuts back on high-fibre food the night before, and drinks UCAN Energy Powder and Hydrate on the nights leading in to the race.
Race morning
Toast, coffee, Tropical Orange
Two slices of toast with almond butter and a cup of coffee. Before the race, one serving of Tropical Orange Energy Powder in water. Sometimes a Strawberry Banana Edge gel before the start.
During the race
One serving every 10 km
Tropical Orange Energy Powder mixed with water, one serving at each 10 km point. Four feeds across the marathon, the last one with 2 km to go.
At the finish
The shake, immediately
One serving of Cocoa Energy + Protein mixed with oat milk, straight after finishing. A full meal with more protein and carbohydrate a few hours later.
Plan as published by The UCAN Company in "Emily Sisson's Marathon Nutrition Plan". Distances converted from miles.
Most race plans end at the finish line. Hers has two more steps and a week of habits behind them.
The shake, before anything else. One serving of Cocoa Energy + Protein in oat milk, immediately. The point is the timing, not the recipe: 20g of protein and 15g of LIVSTEADY™ carbohydrate in the window right after a hard effort, when most finishers are still looking for their bag. The same shake works after a hard long run, which is where it earns its place in a training block.
The meal, a few hours later. More protein and carbohydrate once the stomach has settled. The shake buys the time for that meal to be a proper one rather than whatever is nearest the finish chute.
The weeks before. She lists 8+ hours of sleep in the weeks and months leading in, relaxing activities such as reading and calls with friends, time away from social media, and resistance work with bands: monster walks, lateral band walks, clamshells, RDL pull-throughs and elevated bridges. None of it is nutrition and all of it is recovery.
The daily check. She describes asking herself two questions before deciding whether to push or pull back:
In her words
"How am I feeling?" [...] "Can I push harder today or is it time to pull back and give my body the rest it needs to become even stronger?"
For a runner in a marathon block that question is worth more than any single session. The fuel plan makes the hard days possible. The check-in decides which days should be hard.
Start early
Wake early to run before the heat, and pick routes with shade on hot days.
Electrolytes three times
Before the run, every 6.5 km during, and after.
Fuel every 6.5 km
A gel or a drink at each point. She uses UCAN Edge.
Warm up slowly
A comfortable pace first, then pick it up once relaxed.
Then eat something you want
Doughnuts or a sandwich get a mention. The shake first, then that.
Her original interval is every 4 miles, which is 6.4 km. Round it to the nearest drink station on your route.
Every product in her plan is stocked here. Column two is her plan as published. Column three is how to run it from Australian stock, with the UCAN protocol filling in anything she leaves open.
| The moment | Her plan | With the Australian range |
|---|---|---|
| Nights leading in | Energy Powder and Hydrate in the evenings. | One serving of Energy Powder and one of Hydrate with dinner for the two or three nights before. Food first for the carb load. |
| Race morning | Toast, coffee, then one serving of Tropical Orange Energy Powder in water. Sometimes a Strawberry Banana Edge before the start. | Breakfast 2 to 3 hours out. Tropical Orange Energy Powder 30 to 45 minutes before the gun. An Edge gel 15 to 30 minutes out if the corral wait is long. |
| Every 10 km | One serving of Tropical Orange Energy Powder in water. | With a support crew or personal bottles, the same. Without them, Edge is the pocket version: one every 45 to 60 minutes, no water needed. |
| At the finish | Cocoa Energy + Protein in oat milk, immediately. A full meal a few hours later. | One serving of Cocoa Energy + Protein in the finish bag, with a small carton of oat milk. Within 30 to 60 minutes. |
Run the race-day sequence on two or three long runs first. The drink-every-10-km plan needs bottles on course or a crew; most Australian city marathons allow personal drinks only for elite fields, so practise the Edge version too.
