It has already been established that life on the Liberal Democrat election battlebus is party central.
An insight into what goes on the Lib Dem #battlebus with @paddyashdown #GE2015
But everyone needs a break every so often.
So, on Wednesday afternoon, as the bus rolled down from Wiltshire to Cornwall, the deputy prime minister and his team decided to throw themselves off trees.
They kindly invited the half-dozen travelling journalists, including BuzzFeed News, to join them at an assault-course thing in trees that goes by the name of GoApe. We were told that this is "a break from the campaign on a day when we're in the middle of a three-day visit to seven constituencies".
It was also quite a lot of fun, potentially up there with the visit to the hedgehog sanctuary earlier in the campaign.
We were told to make sure we kept the red and the blue clip attached to the safety wire at all times. Yellow clips were not required.
This is Nick Clegg bravely taking on something which we think was called the "Indian Bridge". It was a lot more scary than it looks.
Shortly afterwards he flew across a valley on a zipwire from a substantial height. It was quite astonishing.
