A London GP is trekking up Everest to raise money for international aid charity Tzedek.
Bronya Gorney reported this week that she had reached Everest base camp having already scaled altitudes of more than 5,500 metres.

Despite avalanches on the mountain which have claimed the lives of a number of sherpa, Ms Gorney's trip has to date been trouble-free.

However, she posted on Facebook that the fundraiser had been physically challenging. "Two days ago when I climbed up to Chukkhung Ri [an altitude of 5,550 metres] I was unable to walk up more than eight or nine steps without having to pause to catch my breath. It was painfully difficult even to swallow water and breathe at the same time. Today I climbed Kalar Patthar, also 5,550m, and could keep a steady upwards climb without much need for a break."

Ms Gorney has so far raised more than £2,000 for Tzedek.
