Sub-Zero Teachers - Preparing for Antarctica

Follow four British teachers as they prepare for their once-in-a-lifetime expedition to Antarctica.

The teachers' preparation schedule includes training sessions on Europe's largest ice-cap in Norway and constant fundraising to earn the £10,000 they need to go. All this is undertaken while they hold down their full-time teaching jobs.

Although the four teachers are excited about using the experience to inspire pupils back home, they begin to realise the toll that such an expedition will take on themselves and their families.
