Idled? That would be a difficult way to make progress- must have been a super idle. You must be referring to Wobbling Wally Watts perhaps- as he is the only one I’ve heard of who unicycled around the world. I’m a bit late in replying though since it has been clarified that circumnavigating the earth is not the objective. Gain some inspiration from Wobbling Wally though- his ride would be a hard one to follow.
