Billy Bolt is gearing up in his quest to win fivefrom-five in the 2025 SuperEnduro Assault , the indoor extreme enduro championship . A foreign concept for Kiwis , with the onset of harsh winter conditions , the slightly nuts European enduro guns do battle in an indoor arena format that lets the huge crowds see what the enduro lads and ladies can do . Bolt has an intro video where he runs through his challenging season in 2024 , where he spent a total of seven months off his bike with surgery and rehab . A very specific type of event , it requires a different training regime as the riders can emulate obstacles more accurately than they can for the hard enduro events where things can change as rapidly as the weather and a more seat-of-the-pants approach is required . The first round was on December 14 but there are six more to run . Fully fit again , Bolt is back in the swing of his training regime and although always appearing super laid-back , as always , he has that steely focus on race day so he would have to be the bookies favourite in the arena-type events .
