The Bathgate pupils are in Greenland thanks to the persistence of their teammate Alex Cochrane, who heard about the project from a previous participant. She convinced her head teacher to sign the school up for the expedition. Since being selected for the team, Alex's confidence and stamina have grown.

The team also includes school staff member Ellis Mackay, who has gained a new understanding of the needs of this group of often-overlooked pupils since joining the project. These youngsters see their confidence and self-esteem boosted by their involvement. The transformation happens with each step the teenagers take in Greenland.

Now they face five hours of hard skiing and their toughest challenge so far - a long, steep climb. The team has to work together, doubling up to push and pull their heavy sleds up the hill. Kimberley goes it alone, and with the summit in sight, Adam steps in to help. The teenagers reach the top, exhausted but elated. They will camp here for the next two days and explore the surrounding area. Day three begins with near-perfect conditions - clear and cold. The team leave their sleds at camp for a day's uphill skiing to their highest point so far. It's an energy-sapping climb and a test of the teenagers' stamina, and commitment, to get to the top. But after a tough three-hour climb they are rewarded with a spectacular view across the Arctic wilderness.

The achievement raises everyone's spirits, especially Kimberley, who has pulled herself up from rock bottom to get here. The team skis back down the mountain to camp. However, on their arrival, Craig has some bad news - the weather has turned and unseasonal wind and rain are heading their way. Greenland has felt the effects of climate change strongly in recent years, with the warm season starting sooner and lasting longer. In 2019 scientists recorded the start of the thaw four weeks earlier than usual.

The team must head back down to lower ground and take shelter. They could be sitting out the bad weather for days.
