Should I attempt a long trip? I daily cycle 20~30 km in (high) traffic going between home, faculty and other places. However I have never been outside of city or in any kind of competition.

Now I have to go to another city and I was wondering if it is a good idea to attempt this journey with my bike.

The route:


180 km, Bucharest to Focșani, Romania.
total ascent 900m (mostly final part)
total descent 750m
national road (100 kph), well maintained, 1 or 2 lane(s) per direction, no median barrier
100% asphalt
passes villages and 2 major cities.


My bike I think it is a hybrid bike (or MTB maybe), but nothing high-end. 

The weather is nice and at return, if that won't be the case, I have to option to take the train (it hopefully should allow for carying the bike).

My main concern is traffic (I am used to traffic, but in the city) and the bike breaking down.

I don't think there will be physical problems from me and I expect to make it in less than 12 hours, but again I never attempted anything like this so...

The prospect of this road trip with my bike really excites me, but I don't want to do something foolish. So should I go for it, or just take the damn bus? If the bike breaks down and I cannot fix it what are my options? Anything else I should be worry about?
180 km is a long way for someone who only normally does 20-30km (to quote @PeterH in chat).

To my way of thinking, you could do it, with some pre-conditions


Do some longer rides, where you ride 30km to somewhere, have lunch, and ride back.
Ride on some of the potential routes, to understand the traffic situation.
Plan ahead, so that you do it over two or more days.


I would check out where other people ride. For example


Strava activities near Bucharest
Strava activities near Focșani. A lot of these go into the mountains, but you may find some that go where you want.


And use Google Street View for reconnaissance.
