Hydrate Like A Heptathlete

 Why Trust Us


We’re all guilty of turning up to the gym without a water bottle… only to fork out £1.50 on a new one, use it once and repeat the following week. Blame it on “decision fatigue”.

We get it… you’re far too busy answering emails to think about refilling water bottles. Let alone wash them after every use. Besides at least you made it to your workout.

But spare a thought for your bank balance and the environment…

If you recycle your plastic bottles after every use, good for you. But in the UK we are failing to recycle as many as 16m every day that could rise to 29bn by 2020.

At the other end of the spectrum, there are those who choose to forgo water altogether. But that’s not doing your body any favours…

“Muscle is hydrophilic so dehydration means it can’t grow properly and we won’t get the best results from our exercise routine”, says dietician Jo Travers.

60% of our bodies are comprised of water and we lose a litre per hour during exercise from sweat. “If you aren’t sufficiently hydrated, your body can overheat. This leads to fatigue and a less efficient workout”, she says.

According to a study of 2,000 people, 44% of exercisers are unsure when the optimal time to hydrate is and only reach for a drink when they start to feel thirsty.

“We should really be hydrating 20 minutes before exercising so that our bodies can absorb the fluids that we will lose through sweating, every 10 minutes during a workout and afterwards to aid recovery”.

The moral of the tale? Carry a reusable water bottle with you at all times. If you’re suspicious of tap water, buy a filtered one like BRITA Fill & Go Active. A cost effective, environmentally friendly alternative to single-use plastics.


One person who wouldn’t dream of exercising without proper hydration is Olympic Heptathlete, Katarina Johnson-Thompson.

Katarina has represented Great Britain in the 2012 London and 2016 Rio Games, is the 2012 World Junior champion, 2014 World Indoor silver medalist and 2015 European Indoor champion as well as the British High Jump record holder.

To get people thinking differently about hydration, she has partnered with BRITA to create SWITCH7. A workout that fuses explosive power moves, strength, speed and agility training, to encourage people to switch up their mundane exercise routines. The session also focuses on how to hydrate properly during exercise, which KJT deems as important as the workout itself.

Join KJT on Saturday 29th April from 11am – 12pm in Finsbury Park to try SWITCH7 and receive a BRITA Fill & Go Active bottle. Sign up to the event here.

As there are limited places, RABBLE the outdoor games collective, will be running a second class on Saturday 29th April 10am – 11am in Finsbury Park. Sign up here.
