Members are also offered the free use of a well equipped workshop and can find friendly and expert advice on all the aspects of bike repairing.

There is also a Challenge Tournament towards the end of the season and the chance to buy our exclusive club sweatshirts and T-shirts.

4 we have a 400 m grass track, field event equipment and one of the finest middle- distance coaches around. Also, an international standard synthetic track has been built next to the University recently. The Club competes all year round, taking part in cross-country, road running, track and field and some fell-running; we are one of the most successful University teams.
