For at least some days of the week walk instead of taking the car or public transport.
More About The Challenge
If you already walk or jog to get to where you need to be, you can claim this one right away.
Walking may take longer and jogging may seem a bit daunting at first, but alongside the environmental benefits, this is a great way to work on those glutes.
If you don't walk or run every day, that's fine, any step towards less pollution from traveling is a good one.
Why Is This Challenge Important?
Along with the cycling challenge this is a super efficient way of reducing CO2 emissions.
Emissions from vehicles are contributing to the buildup of CO2 in our atmosphere. This has been linked to climate change, which is obviously a big deal - most of us are aware of it by now and this is just one step towards tackling it.
Alongside climate change, there's also poor air quality and traffic buildup.
Cities that see people using their legs to get around also tend to build infrastructure to suit them. This can lead to safer and more pleasant looking pedestrian only streets or walkways.
