I cannot speak to any Eroica rides in other countries but I have ridden Eroica California (EC) here in
my home state in the past.
Although the initial EC rides were well done, they have received less and less support from the Italian organizers
recently so I am not sure whether I will participate again.
I DO love the swap and the socializing with fellow classic steel bike riders and fans but the lack of support - apparently due to a lack of engagement from the Italians and a lack of understanding on their part about how we organize events here in the US - of late has been a real downer. (I cannot speak to any other Eroica rides in other countries.)
