Today I did the last part of my journey, cycling the length of one of Mother Thames's favourite daughters, the Lea (or Lee). I've also checked off most of Lea's nephews and nieces in the form of the major tributaries  Rivers Ash, Beane, Mimram, Rib (Quin), Stort; And the brooks, Bayford, Broxbourne mill, Spital, Small River Lea & Turnford, Wormleybury. With each of these, I've gone as close as I can to the source and then followed towpaths, bridlepaths or roads as close as I can to each stream all the way to where it joins the Lea and ultimately the Thames. 

At some stage to do this properly I should probably check off the rivers Moselle and Ching.  And at least the Cuffley and Turkey Brooks. There's also the Limehouse cut to follow. 

Today's journey was from Ware to Leamouth where it joins the Thames and back again with a diversion to Victoria Park and the Hertford Union Canal Cut. The catch was the NE wind behind me on the way down and in my face on the way home complete with a few minutes of driving rain. It's always a pain when the hard work is on the way home!
