PlayCatch up with the action from the third episode - and watch clips from the recruits' encounters with huskies...
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.
It's soon clear that shy Barnsley lad Anthony isn’t liking it one bit. The gym environment provokes a crisis of confidence, and brings back uncomfortable memories of school bullying. It takes all Jack’s leadership skills to get him back on track.
The day of the big run dawns, and Jack leads the team, rolling down concrete steps and jumping from high balconies. In an exciting sequence, running alongside the UK’s premier free running crew, Jack and his recruits perform well – even Anthony.
What should be a period of celebration at their achievements is marred by conflict within the group, as tensions between Lisa and Georgie surface again.
Jack brings his team together, and tells them to resolve their differences and work as a group – crucial advice given their next destination. They're off to the Arctic mountains of Northern Finland, where the team will do a hardcore dog sledging trip into the heart of the frozen wilderness.
After arriving in Finland, Jack and the team undergo the briefest of training, and must get kitted out for temperatures that can drop as low as minus 30C. Their means of transport are sledges pulled by five hardy huskies each, and the team work hard to keep control of both ride and beasts.
Just as the team get into their stride, there's a snow storm, but they still need to pitch their tents in the plummeting temperature. Surviving their first night out in the icy wastes, the team must cross a high, potentially dangerous plateau. It soon becomes clear that all is not well with Jack – he clings onto his dog sledge to make it to the next camp, where the plan is to dig snowholes to provide relative warmth.
Jack is too ill to help dig, and rests in an emergency shelter, while the recruits labour into the night on his behalf. There is an upside – the shared adversity brings Lisa and Georgie closer together, but the recruits can’t work fast enough to get the snow holes finished. They have to spend another night in the tents with Jack, who's becoming more and more ill by the minute. With the temperatures moving towards minus 30C, and Jack vomiting onto the ice beside his sleeping bag, has he pushed it too far this time?
