The challenge involved renovating a dilapidated old school building into a nursery for Leeds Mencap in 55 hours. Additionally, from the thousands of paintings sent in response to a radio appeal, Anneka had to select a winning entry and have 25,000 copies of a Christmas card produced in time for the nursery's opening.

The 72 hour challenge involved transforming a derelict shell of an old building into a recreation/sports centre for the Greycraigs Outdoor Centre in the Isle of Cumbrae. The climax was a rally of 1,000 cyclists arriving at the renovated building at the deadline.
