I was driving somewhere yesterday and came across a peleton of cyclists, about 15 of them, spread about 50m apart. I was on single track back roads. There was a car in front of me but it was a mini and was able to get past more easily. When the road widened I tried overtaking but because there were so many of them and they were quite spread out it wasn't that simple. A car came towards me so I had to split the group up and pull in. This went on for at least a mile and then I needed to turn left. I was still trying to get past them at this point so I indicated and stopped in the road. If it was a car they would have waited behind me but some of them undertook on the inside. Some of them waited behind shouting abuse at me. I genuinely did not know what to do. Obviously because they were a big group and so spread out overtaking them had taken a lot longer than I expected and I didn't realise that I would need to turn before getting past them. The road stays single track for a long way. I really don't think it is appropriate for such a big group of cyclists to be riding on roads like that and if they do need to they should split into smaller groups so that cars can pass safely. WWYD in this situation?
