What to eat before a triathlon depends on the distance and on what you have practised. The rule we give every athlete at our Samford gym is simple: nothing new on race day. Everything below should be rehearsed before long training sessions first.
The night before
Eat a normal, carbohydrate-focused dinner you know sits well: rice, pasta or potato with a moderate serve of protein and not too much fibre or fat. This is not the time for a large salad or a new restaurant. Drink normally through the evening.
What to eat before a triathlon on race morning
| Race | Timing | Example |
|---|---|---|
| Sprint | 2 to 3 hours before | Toast with honey or banana, a small coffee if you usually have one |
| Olympic | 2.5 to 3 hours before | Porridge with banana, or white toast with jam, plus a drink |
| 70.3 and longer | 3 hours before | A larger carbohydrate breakfast you have practised, plus fluid with some sodium |
Keep fibre and fat low on race morning. Your gut will be nervous enough already.
The last hour
Sip water or a sports drink. For Olympic distance and longer, some athletes take a gel 15 minutes before the swim start. Only do this if you have tried it in training. Get to transition early so you are not rushing, and keep a familiar snack in your bag in case the start is delayed. A late start with an empty stomach is a common way to fade on the run.
Practise in training
Use your long weekend sessions as rehearsals: same breakfast, same timing, same drinks. Our pre workout snack guide has more on eating before training generally.
Day to day, not just race day
Race-day food is one job. What you eat every day through a training block is another, and that is where protein, gut health and joint care come in. Propel Health Australia has set out the short list, in the order a coach would add it, in this guide to supplements for triathlon.
Common questions
Should I have coffee before a race?
If you drink coffee normally, have your usual amount at your usual time. Race morning is not the day to try a bigger dose.
What if I cannot eat because of nerves?
Try a liquid option such as a smoothie or a sports drink, practised in training. Something is better than nothing for Olympic distance and longer.
Do I need to carb load for a sprint?
No. A normal carbohydrate-focused dinner the night before is enough. Carb loading over a couple of days is for long-course racing.
When to get it checked
If race-day stomach trouble keeps coming back despite practice, get help from a sports dietitian. For training load and recovery, an exercise physiologist can look at how your week is structured.
