In addition to selecting and sending elite junior and senior teams to the European and World Championships, the association selects Age Group Teams. These are selected according to the association's published Selection Policy and involve association members qualifying through a series of races held in Great Britain. Lists of qualifying athletes for the current year's ITU World Championship and ITU World Long Course Championship are maintained by Ian Pettitt, the list for the ITU World Duathlon Championship is maintained by Jasmine Flatters. The official Guide to competing for Great Britain in 2001 is now available online for anyone interested in applying for a place in a GB Age Group team. The Team Managers enter athletes qualifying for the GB Age Group Teams and travel as part of a small management team to the championships to support team members.
Members selected are responsible for their own costs.
The association has a Travel Agency who will arrange travel and accommodation for team members at competitive prices. Team members are also eligible to purchase and wear the Great Britain International Team Kit designed by ORCA, which can be purchased directly from Tri-UK, the association's appointed distributor. To assist current and potential age group internationals, the association runs a series of Training Camps both in Great Britain and overseas. These camps are designed specifically for athletes aiming to compete in the European and World Championships as an age group athlete.
