The show also draws its inspiration from the 1980s TV series "The Great Egg Race". The UK show was originally presented by Robert Llewellyn, joined in series 2-4 by producer
Scrapheap Challenge by RDF Media, and was originally shown on The Learning Channel. Repeats have aired on another Discovery network, the Science Channel.

The final showdown usually consisted of either head-to-head races or individually run timed
