The award for the first contest in 2005 would have been US$50,000, if the challenge was met. The requirements of the challenge was that the wining team would construct the strongest tether.

In 2005 no team was able to beat the baseline house tether.

In 2006 the challenge requirement is that the winner outperform that of the previous years winning tether by 50%, and beats the other challengers. The prize for 2006 Tether Challenge was increased to $200,000. [2]
