Rear LED light while cycling along Regents Canal.
Cycle maps.
1) I lost the NCN map for the northern part of the Lôn Las Cymru ride while doing the ride. We had gotten lost in a wood & spied the track we needed, but to get to it required pushing the bikes down the valley side, which was a forest. When we escaped the forest and were on the track we needed we realised that the maps had been swiped out of the side pocket of the rucsac by the trees. We knew the name of village that we were heading for, but with no map we didn't have a clue how to get there. Ended up having to ask a passing farmer for directions.
2) When crossing the Afsluitdijk in The Netherlands I lost the map of friesland, which was in my jersey pocket. That covered the next part of the ride I was doing, but fortuantly it was well sign posted and I also had a regionally map of the netherlands and I didn't get lost cycling through friesland.
