Interesting thread. I was at Swinley this weekend with my 7 year old and 4.5 year old daughters and I can see both sides of the debate.
The youngest was on a LOCT seat and attracted (as usual) polite and friendly comments and my oldest was on her <proud dad> custom built 20″ bike. She got loads of comments and “well done’s” from people which is brilliant for her confidence.
We were a lot slower than most but I tried to ensure we moved out of the way as soon as possible to let others past and we got plenty of “thank you’s”.
However, I also came across people trying to cycle round in flip flops on quite tired looking bikes and I did wonder how they would get on.
I think the regulars know an early start is best for a more flowing / own pace ride but I think we’d lose a lot if places like Swinley didn’t exist and allowed a mix of riders.
It’s proving to be great training ground for my kids (who’ve been LOCT passengers for years) and who are now experiencing the fun and exercise for themselves.
