Assuming it hasn't changed since 01, bike is undulating with long slight inclines and declines, nothing steep. Bit along a dual carridgeway but mostly rolling b roads and a bit through the back of swanley to get you out of the centre. Run was 3 laps of the park which again was flatish and no way the 8km they say it was, it took me 34 minutes when I couldn't run 8km fresh in less than 36!
Swim is flat :o)
Good luck and have fun.
