The Upper Thames 200 delivered 91 more tiles and increased the cluster by 11. I took the west bank of the Thame from Chalgrove to Wheatley to pick up 6, but missed one because a previous GPS funny made me doubt myself, so I ignored the turn.... A couple more excursions from the route on the drag up to Chipping Norton. Slightly kicking myself for not picking up the Soho Farmhouse one, which would fill a gap. I'd planned to pick it up on another ride, but now that I've been past it, I should have done it. It would have only added a km or so to the route.
Then one final off route excursion to fill a gap in Wychwood Forest. Down a muddy bridleway, the GPS beeped to say I was off route, went a bit further, hung around for a wee, then got home to discover that I still hadn't quite caught it, by a matter of feet, I expect. Frustrating...
Also, if I'd followed the diversion to avoid the flood near the start I'd have had two more tiles AND dry feet
