Of course pedestrians can travel on the Eurostar trains through the Channel Tunnel (with limited options for transporting bicycles), but that's not what I mean. My question is: can pedestrians and/or cyclists board the shuttle trains between Coquelles, France and Folkestone, UK? If yes, how does it compare price-wise with the ferries? (For cars, a tunnel is significantly more expensive than a ferry.)
Oh, and I also don't mean cycling through the Tunnel like Chris Froome, even though I'd love to do that.
