Charlotte Read, Bradley Weller and Josh Weller, who all work for Leaders, joined friend Tom Gilbert in the four-day trek. The fundraising event was in memory of Rob Gauntlett, 21, who died while climbing in the French Alps three years ago.
Money raised will be donated to the Henry van Straubenzee Memorial Fund, a UK-registered charity which aims to lift Ugandan children out of poverty through education.
Josh Weller said: “We started our walk in Winchester and finished at Beachy Head with sore feet and aching joints. We were so pleased to have completed it and raised almost £3,000 in Rob’s memory for a cause that we know he would fully support.”
