Train indoors and outdoors
‘Ok, so during the winter you’ll have to train in a pool,' says Brownlee. 'But when it gets warmer you should practise in open water so you’ll know what to expect during a race. You want to do one speed session and one distance session per week.’

Get some coaching
‘It’s a good idea, no matter what your level,' says Brownlee. 'Even if you’re doing loads of training on your own, there could be crucial technical aspects you’re getting wrong.’

Warm-up properly before the event
‘I do two or three sprints of around 20 strokes and go for a short jog just before a race,' says Brownlee. 'Keep moving around right up until the race starts so your muscles are warmed up.’

Make sure you have enough in the tank
‘I have a good breakfast on the day of the race – something that’s packed with slow-release energy, such as cereal or porridge,' says Brownlee. 'I’ll have an energy bar just before the race which delivers a quick-hit of fuel.’

Be prepared for some argy bargy
‘The first 200 metres of the swim are really frantic,' says Brownlee. 'People will try to get past you by grabbing your shoulders, pulling your suit down or elbowing you in the face. If you’re new to triathlons and are more concerned about finishing than winning a race, I’d recommend starting on the outside of the pack. That way you’ll avoid the worst of it.’

Slipstream to save energy
‘You’ll want to save energy for the next two stages, so ideally you want to find someone who’s slightly faster than you and get into their slipstream,' says Brownlee. 'If you swim on their feet, they’re breaking up the water so there’s less resistance to slow you down or tire you out. It’s also important to scope out the route so you know where you’re going – you want to take the fastest, straightest line between the buoys.’

Break up your breathing
‘Normally people breathe once every two to five strokes,' says Brownlee. 'If you take a breath every stroke it will stop you building up the kind of speed that two or three strokes in a row generate. If you’re in a scrum someone could stop you lifting your head out of the water when you plan to, so you have to be able to break your breathing pattern. You should practice breathing at random intervals during training – look up every ninth or tenth stroke to get your bearings. Just make sure it’s a continuous part of your stroke or it will slow you down.’

Use your arms more than your legs
‘Your arms should be doing most of the work so you’ve got power in your legs for the next stages,' says Brownlee. 'You need to reach ahead with your leading hand while raising your other elbow so you’re pulling water back with a sculling motion. The most powerful bit of the stroke should be from when your arm passes under your shoulder until it comes out by your hip. Pull it out of the water in a relaxed manner so it can recover a bit for the next stroke. Kick from your hips and keep your leg straight so the whole limb is generating power.’

Get the right wetsuit?
‘You need one that’s buoyant and gives a lot of freedom of movement around the shoulder area,’ says Brownlee.
