Is there already a map available or how do you know it's going to be technical?
Remco's certainly not the best TT bike handler in technical TT's but if he can properly prepare for it and sets his mind to it, he's definitely no slouch either. I have no idea however how he stacks up against Tarling on a technical level but according to your post Tarling must be pretty good also in that aspect?
Tarling's extremely good technically yeah. If you go through all his TTs can see that. F.E. looked far superior to Wout through some of the corners at euros. Remco I would say is only passable at best technically, generally loses a bit of time through all corners.
Kinda off topic, but TT technicality is in general a bit weird tbh. Kung (when he's looking where he is going) is probably the best in the world through corners in TTs. The best since a certain Fabian Cancellara. Certainly wouldn't say that for the rest of his racing.
Also yeah, LFR has a map of the route working it out from the profiles provided and start and finish points. I've since went through most of the route on streetview. It's not a crazy technical course, although it has some very fast and scary looking descent sections tbh lol, just significantly more than 2023 worlds, which had very few corners.
