In this show, Tim took on the ten greatest bets in history.

In this first bet, actor Hugo Speer challenges Tim to roll a cheeseboard four miles in only 100 throws.

In this second bet, and my personal favourite, comedian Alex Horne and Tim bet on the outcome of a race: can Tim cycle from London to Dover and back again, in the time it takes Alex to draw a million dots?

Then a more straighforward head to head race. With a racehorce...

And finally (for the website, not for the show!), Richard Hammond bets that Tim can't push a wheelbarrow from Ware (Hertfordshire) to Shoreditch (London).
