I did it last year. Went down to BeSpoked in Bristol. However,rode riverside paths out of London, then from Windsor back on quietish roads till after Hungerford. Even then it was a bit rough off and on till Devizes and I went on to the country lanes around Etchilhampton at one point. Got bogged down in mud which as I was carrying camping kit wasn't great! From there the K&A is fine though. So, if you're planning to follow the waterside paths all the way, it will be a tough ride. Im not sure its absolutely worth it, because the countryside lanes are lovely too. And much easier! But then Im getting old. If you have the time, its worth stopping off in Bradford on Avon. About a mile up from the village centre are the Moulton workshops. I was lucky enough to pop by when they had a bit of an anniversary gig going on. Fascinating array of Moultons on display.
