Just back from a ride into Oxford to buy a lock for my new bike. Got off to a bad start as after a mile or so, found the road closed by police (apparently there was a tree fallen across the road) so retraced my steps (tracks?) and decided to take a little used lane to just past the problem. Unfortunately, all the traffic coming up over the Thames at Newbridge had to been diverted to come up the lane I was going down. A couple of large vans had met and blocked the road - I was able to get through going the other way by walking on the verge, but there were a lot of cars and all wanted to know what was going on. Progress was slow! Finally made it to the far side of the blocked road, over the river, up the hill and away, though Appleton and on to Cumnor, bridge over the dual carriageway and down Cumnor Hill to Botley, then a short ride along the cycle lanes to Warlands cycle shop. Nice chunky lock purchased from and fitted by proprietor, so after a bit of a chat I was on my way. Carried on through Oxford and out to the A40 which has a cycle lane all the way back to Eynsham, then B roads to Northmoor where I treated myself to a plate of Welsh Rarebit and a pint. Home via the previously troubled lane to find I had ridden just over over 31 miles, or just a few metres more than 50 km. Very satisfying!
