There's nothing worse than being on track for a new PB then having to stop mid-race for a toilet break. The best case scenario is that you just need to quickly relieve your bladder – but at the other end of the scale, you may be cramping up with major gut issues.
Don't worry, though – there are solutions to your stomach woes! We chatted with top gastroenterologists and athletes to identify nine strategies to help you make it through your next race without bad toilet experiences.
1. Add food and bathroom habits to your running log
Keeping a log of what you eat and how often you visit the bathroom will help you to identify your gastric triggers.

'We are all different in how we react to specific foods,' says Hardeep Singh, a gastroenterologist at St. Joseph Hospital in California. 'The best thing to do is to track what foods you eat and how that correlates with your bowel movements in the weeks leading up to a race.'
This can help you to identify foods that may cause you to run for the bushes during those training runs. According to Singh, common triggers include lactose, sugar substitutes, wheat, gluten, soy, caffeine and eggs.
2. Improve your running form
It takes the average runner 1,000-plus strides to cover a single mile, according to the American College of Sports Medicine – that equals a whole lot of intestinal jostling.
An easy way to decrease the trauma to your innards – and to Race to the loo? No thanks. How to avoid toilet breaks during a race – is to minimise your vertical oscillation, or how much your body bounces up and down with each stride. Many running watches How to do a single-leg squat.
On your next run, imagine that a ceiling is one inch above your head – as you move, try not to hit it. Incorporating eccentric leg exercises into your strength-training routine – where you simply slow the 'down' portion of exercises like squats or lunges – can also help you to naturally minimise bounce. That’s because eccentric exercises strengthen your muscles while they lengthen, which is exactly what happens in your hips and calves every time your foot strikes the ground. So, when you increase your eccentric strength, you reduce how much your body drops (and bounces back up) with each foot strike.
3. Taper your fat and fibre intake
One to two days before your race, try to reduce your intake of fat and fibre. This will mean that you don't have any more food than absolutely necessary hanging around in your GI tract when you cross the start line. And, according to John Pandolfino, chief of gastroenterology and hepatology at Northwestern Memorial Hospital in Chicago, it also means that you don't beeline anything you consume during the race all of the way through your intestines before you cross the finish line.
That’s because dietary fat slows digestion and is hard to break down in the gut – and since blood flow is diverted from the gut and toward the muscles during exercise like running, you don’t want to make any mid-race digestion more difficult than it needs to be. What’s more, while fibre helps to keep your bathroom habits regular during training, when combined with pre-race jitters and race-length workouts, it can contribute to diarrhoea.
In the days immediately before your race, cut out any rich or fatty foods such as creamy sauces, fried foods and potentially whole fat dairy. Be sure to switch from complex to simple carbohydrates – such as white bread and white rice – as well. Pandolfino also urges runners to avoid cruciferous vegetables like broccoli and cauliflower the day before a race if these often cause trouble.

'A lot of athletes do this,' she says. 'You want to aim for 15g of fibre per day, two days before your race. It's not fun because you are cutting out fruit and vegetables which you need in the long term – but it actually works very well if you only do it before a race. I tend to eat oats for breakfast, chicken and rice, then Rice Crispies as a snack.'
It is also best to avoid spicy foods, as these can stimulate muscle contractions in the large intestine – particularly several hours to a day after consumption.
4. Tweak your caffeine routine
Many runners have a love-hate relationship with caffeine. While the fatigue-fighting compound can definitely improve exercise performance – which is why many gels actually contain caffeine – Pandolfino says it can also send your bowels into high gear.

Still, while the amount of caffeine each stomach can tolerate is unique, the gels might be a little easier on your stomach than pre-race shots of espresso. That’s because research also shows that various compounds in coffee increase the body’s levels of gastrin and cholecystokinin – two hormones that speed up how long it takes things to move through the gut. With that in mind, any coffee is usually best consumed at least an hour before you start your race. That way, you have a good chance of completely emptying your system before you get going.
5. Get your nerves in check
Butterflies in your stomach aren’t as pretty as they sound.
'Anxiety that goes beyond supporting performance to the point of hindering performance can also stimulate muscle contractions in the gut, leading to bowel movements including diarrhea,' explains David Clarke of the University of Connecticut School of Medicine.
'The brain and gut are directly wired to each other, and any stressor can contribute to a change in bowel habits,' continues Singh. So, the best way to keep pre-race jitters from going straight to your gut is to try to eliminate any anxiety that you don’t find motivating or energising. After all, while a certain amount of adrenaline can be helpful during a race, too much can make you feel like (and go for a) Number 2.
Everything from taking slow, deep breaths to laying out everything you need on race morning the night (or even two nights) before can help you to eliminate excessive stress.
6. Schedule a pre-race toilet trip
'If you can get on a regular schedule, ideally you should try to time it so that you have a good healthy bowel movement a few hours prior to race time,' says Singh. That way, you’ll have the least amount of food in your system during the race. Running causes your body to divert blood from your GI tract to your muscles, which, if you have much of anything in your system, can contribute to diarrhoea.
7. Slow down your fuelling
'In general, eating and drinking slowly during a race is helpful at preventing gastrointestinal distress,' notes Singh. Sipping and nibbling slowly allows your gut to absorb nutrients efficiently with as little work as possible and minimises any stomach grumbling. By contrast, quick eating or gulping generally involves swallowing some air, which can lead to gas, cramps and, eventually, a bathroom break.
That said, it’s important to avoid under-fuelling. When you reduce how much you eat or drink during every fuelling session, you'll need to increase feeding frequency proportionally.
8. Drink electrolytes
Although drinking fluid may seem counterintuitive when it comes to preventing toilet visits during a race, staying hydrated with the right type of drink is key.
'Stay hydrated by drinking plenty of water and electrolyte-rich sports drinks before, during and after your run,' says Clarke. 'Dehydration can lead to insufficient circulation to the gut during running, which can contribute to digestive issues like diarrhea.'
9. Use the toilet and catch-up
Going for a toilet stop mid-race might not be as time consuming as you think. So, don't stress if you do divert for a quick loo break, because the rest from running may help you to catch up. Molinaro experienced this in a recent race and found that she didn't lose any time.
'As soon as the race started, I really needed a wee,' she says. 'I was stressing myself out. There was a portaloo on the way and I just stopped. It took me five seconds and then I caught back up with the people I was running with really quickly. I didn't actually lose any time and I felt so much more comfortable.'
Molinaro says that one tactic is to research in advance where the toilets will be in a race, then build this into your race plan. That way, you won't feel stressed about not wanting to stop.
