After her last adventure (the Namibia Ultra-Marathon) we thought Helen from Blue Peter couldn't come up with any crazier adventures. However, this time, she's off to the Amazon and she's going to be canoeing from one end of it to the other!!

The BBC have once again asked if they can have use of a Yellowbrick in order to track Helen's progress along the way, and we've of course obliged.

We wish Helen the best of luck, and we'll be posting updates as and when....
