There are 57mm reach road bikes out there... with the caliper reach close to maxed out bikes @ this spec will fit 28's with fenders, or 33's without. The problem is that this often isn't mentioned in bike marketing, so you have to do some digging to find this kind of bike.
I got a Brodie Remo this year that's really a nice frameset... nimble, quick handling road geometry with 57mm reach brakes so you can fit big tires and fenders. The build you get stock is fairly meh, but you can hang your own parts on the frameset to build a very nice distance bike.
As road discs get more popular I think it'll get easier to find capable road bikes---like, not cx bikes or especially heavy commuter frames--- that fit big tires and fenders.
