i'm out (obviously) which is a shame since i love london _ cambridge.

one comment on the route: near the end you are by great shelford and there is a very cool cycle path from there to addenbrookes hospital that runs next to the railway line. totally off road with a lovely surface. it is painted in 4 different coloured stripes, representing (A G C T) and it spells out one of the genes mapped in the human genome project.

which is nice.
