The RideLondon Classique Women’s race that went alongside the whole RideLondon weekend was moved (apparently by the UCI and without consultation but who knows…) so without that, it becomes a whole load of expensive road closures for very little return. If you can have the Women’s race (and the resulting tourism, TV coverage etc) it’s viable but without that it’s like the London Marathon but 10x as disruptive and costly.
London wasn’t able to just go “oh OK, we’ll do that weekend instead” because these things take years to plan and you can’t just change dates at the drop of a hat.
I did the original Box Hill event a few times, was good fun.
As they say though, it could probably do with a bit of a refresh anyway, here’s hoping it comes back for 2026.
