River Cam 5m 17 October 2010 John Howe reports: This was a very nice, well organised, low key run with practically no road and mostly tarmac paths, and some off road at the end. The weather, and absence of hills contributed to the enjoyment, but it would be another story on a wet and windy day. It certainly will never be a PB course as you have to negotiate quite a few cattle gates/grids, a stepped bridge over the river and 3 latched gates in the last mile.
