Bryony Balen and her team are now over 50km into their expedition to the South Pole, and are on track to reaching their goal in time.

They have described the weather as being "fantastic and beautiful" with a spell of various sun halos appearing during a particularly long 18km stint.

External temperatures have reached an incredible 4°C above zero, but as the team have discovered, this is not necessarily a good thing. Bryony has been forced to take more rest breaks due to overheating.

Overheating, brings with it an array of issues that if not addressed can be just as lethal as the cold. Being too hot causes sweating, which will conduct heat far better than air within the many layers of clothes, allowing heat to easily be leached from the body and cause hypothermia. During skiing the team have been removing their outermost layers to avoid such problems, putting them on when they stop to rest.

As a supporter of twenty one year old Bryony Balen’s British Antarctic Record attempt, Butler & Willow will continue to track Bryony’s adventure every step of the way.
