Basically my third time out. Not that I’m recommending that route.
I would not suggest taking an hour long ride for your first time on the freeway. Depending on your steed freeway speeds can be quite tiring. However they are not hard to ride. You almost never shift or brake. All the traffic is going the same direction and lanes are wide with good site lines. But everything is moving much faster with lots of wind noise and more wind gusts to knock you off your line.
I only did about 15min but it was tiring on my Ninja 250 without earplugs. When I got back on the freeway later that day I used ear plugs and they helped tremendously.
For your trip I would suggest looking for an alternate and avoid the freeway if possible. It is much more fun and rural road are much better than urban.
