Your hybrid is a lot better ride than some others I've seen out on the road. It'll be just fine. A bit slower maybe than a standard touring bike, if there is such a thing, but a tour is not a race.

30kg is actually a lot of weight for a tour. I always say if it weighs more than 20kg, you've packed too much. Common for novice tourers to overpack. Do an overnighter or two and see if you can do without some stuff.

Adjust the gearing so that your pedaling cadence is in the 60-80 rpm range. More efficient, less tiring.

Above all, have fun.
