On the part I know, you can avoid Didcot by continuing from South Moreton through North Moreton to Appleton. It is generally a good idea to avoid Didcot.
Apart from that, it looks fine. Pangbourne can get busy, but the only way to avoid it is to go through central Reading which is busier.
Mini and I had a crack at the Brighton - Oxford leg yesterday. That's the furthest I've been on a bike in one hit.
Only two mechanicals; the first was my rear mech cable snapping at the brifter about two miles north of the A27, and my Wahoo clamp screw dropping out.
Sorted the mech by winding the limiter screw in (and I have a triple, so that gave me a mildly usable set of gears, except that the bike has had so little use recently I had to use a heel tap to get it into the granny ring).
I watched the screw drop out so that was found after only a couple of minutes of searching (on a thankfully very quiet road).
All in all a great day out. I was pooped by the end of it but mini was fresh enough to do another 25 miles to Henley. Oh to be that young !!
Rod,
Massive thumbs up for the Didcot avoidance suggestion. What beautiful roads with stunning scenery and hardly a car in sight. To add to the delight the sun came out when we got to about here. Mini was blown away by it all. Many thanks for taking the time to suggest that.
Pangbourne was fine.
ETA. A massive thumbs up for Evans Cycles in Guildford which was on the route so no diversion required whatsoever other than to bump up onto the pavement. The workshop team provided me a cable, an end cap and lent me cable cutters/crimper and wouldn't take a penny. Amazing stuff.
