To complete this type of race you have to have a support crew with you, for a variety of reasons. The obvious one being health and safety. Adam would be cycling and running on open roads in the Snowdonia area for the next three days. No roads would be closed so you have a whole list dangers to consider such as other road users, tiredness and fatigue, navigation of the course, food / hydration, bonking (a phrase used by endurance athletes where extreme fatigue sets in and your mind starts to play tricks on you), equipment failure, changes of clothing and the general well being of the athlete.
The organisers of the race Darren, Ben and Claire were great. They all had very respectable experience in ultra-endurance events both as athletes and crewing. They were extremely helpful and friendly throughout the event answering any questions and dealing with any issues promptly. They went through all of the 'need to know' information about the routes for the swim, bike and run and were clear and concise all the way through.
The first day would consist of a 6 mile (10km) open water swim in Lake Bala followed by a 90 mile cycle from there heading back towards Betwys y Coed. Each athlete was given a GPS tracking device which they needed to wear at all times during the race. The device was linked to the headquarters back at the hotel where they would also monitor the progress of the athletes on each day. If any of the athletes went off course or there was an issue with the device the HQ would call the support team to resolve the problem as quickly as possible.
