I've done 200k audax with 50mm GK SK+ tyres on. It wouldn't be my first choice for a road race but if you're not racing does it matter if a road ride takes a bit longer?
Actually I just had a look because we did the same route on road bikes and I was 45min slower on the gravel bike off a 10W higher NP. 4600kcal vs. 5200kcal on the gravel bike. Definitely a difference (obvs, knobby tyres vs slicks!) but unless you're racing does it matter? It doesn't to me, that's why I favour more durable, heavier tyres until there's a stopwatch and finish line involved.
This is a fair point. Probably makes zero real difference, other on proper hill climbs perhaps.
Currently I use 38/40mm (the specs say both 🤷♂️) G-One Speed (effectively slick) having had enough of Gravel King slicks in the same size.
I think I'll save the cash [edit: or buy a pair of Contis if I suddenly decide to ride up a non-virtual Alpe]
