Well that was fun. We got the London Overland train to Kew Gardens and then set off down the A315. Being a single carriageway Roman road makes the A315 a great way to escape London, esp. at 10 am on a Saturday morning 'cos it was still relatively quiet. Disaster nearly struck at Honslow when one of the bolts on my rack worked lose (I'm assuming I didn't tighten it enough, tho I'm not entirely sure what happened). Fortunately I had a spare bolt and the thread was not sheared or else Nienke would have been carrying the panniers. The A3113 road past Heathrow was horrible, but it didn't last very long before we out over the M25 and onto leafy roads. Going through Eton was fun because I've never been there before, but the road through Eton Wick (the B3026) was busy and narrow. We therefore decided to take NCN4 from Eton Wick to Dorney just to avoid that road, which was a mistake. The route goes across what felt like peoples lawns, not even on gravel tracks. A really stupid route. I do not recommend it.
After we had fought our way through Maidenhead things rapidly improved. The lanes around
Cookham Dean were lovely, as was the pub lunch at The Jolly Farmer. Mmmm. Getting through Marlow was straightforward and then we were onto little lanes all the way to Oxford and basically every junction was straight on, making the navigation really easy. These lanes would make a super duper night ride! There were two main hills, one coming out of Marlow and the second one was between Turville and Christmas Common.
Going through the Chitlons was lovely. We saw a red kite and some other big birds of prey and it was a beautiful autumn day, with various colours in the trees and bits of sunshine appearing through the canopies of the trees and lighting up the sunken lanes. After Christmas Common we swooped into the Thames valley and start looking for signs of the Oxford spires. Overall, a great route and a route I'd recommend to other people.
PS: There were no trains running between Oxford and Didcot and so we got the
Oxford Tube back to London, which was fine because they take bikes on the coaches. Something worth remembering.
