Got up early this morning and put in another 21 miles, I learnt that when signs say a footpath is closed due to flooding it's usually correct. At points it was over my chainset, after pushing on through a couple of sections I gave up and came back. On the positive note I found somewhere I can train on a flat car free route and there's some gentle off road either side. The St Ives to Cambridge guided bus route, it's got to be good for something! A 30 miles round trip from home and I'm building up slowly, I really need to refine the 50:50:50 and start speaking to bike clubs for their ideas.
