After four adrenaline-soaked weeks away in New Zealand and Borneo, Jack and the recruits regroup in London for their next adventure. The challenge: to run a route though central London. Sounds easy? This being Adrenaline Junkie, they're going to do it the hard way by joining a hardcore team of urban runners, who are going to do the run parcour style. Jack and his recruits will use stairs, handrails and balconies to create their own obstacle course through London’s streets, and they've only got two days to get their skills up to scratch.
