I ride a 650B gravel bike with somewhat knobby tires everywhere, and I'm definitely slower than the serious roadies(at least they LOOK serious considering their kit). Where I live it's all incessant climbing, whether on the road or the dirt. I'm strong and can ride forever, but I get passed all the time. I think it's a combination of my engine, my bike, but also just the way I like to ride - I'm not in a hurry.
