Both would fit 38mm quality road tires that will be fast and comfortable.
The cervelo is $4000 and the trek is $2900.
This assumes you want a 2x11 drivetrain. Makes sense since you will ride it on pavement and climb.
The cervelo has a wider range of gearing to help with a wider group of people when it comes to climbing. No idea if you need that.
Either way, pretty choice bike centered around a single ride.
