Can you guys share your input when it makes sense to go for a fast carbon running shoes vs a comfortable one?

I always imagined that I would run in Alphaflys which is a great shoe for me in regular marathons. However I don't know if it makes more sense to go for a more comfortable shoe like Vomero Plus for the Ironman marathon.

The reason for that is because almost 25 % of the course is gravel which isn't great for carbon shoes, and also because I expect a pretty slow marathon in 4 hours or so. So I expect I will not benefit a lot from the carbon and should maybe go for a heavier/comfortable shoe.

Can you share your thoughts? Thanks.

How bad are the cobble stones? Will bottles fly left and right? After watching Paris Roubaix I'm a bit worried.

Can someone who previously raced Hamburg share their experience? They have changed the route a bit, but seems like cobbles stone are a still a part of the route.

Thanks!
