Hi atticus I have raced duathlons for 5 years-love em!. My tips would be- Enter a low key local event 1st off,enjoy it and don't worry how slow/fast you finish. If you enjoy it then look to get fitter by maybe joining a tri/running or cycling club and training with them. Most clubs have a wide range of abilities so you will not feel threatened at all. As someone said above,crystal Palace tri are a good club and very friendly.I was a member for a couple of years. How is your fitness?,can you run and cycle ok?,if so how far?. There is a good race over at Hillingdon cycle circuit on Nov 14th (i think) run by Hillingdon tri. Nice friendly event and all held on a traffic free circuit.i think the distances are- 1 mile run/10 mile bike/1 mile run. Most duathlons now go off road for the winter until early spring PM me if you like C
