Cycle from Ljubljana to Koper alone

I am not quitting on that one. Opposite to running, which I prefer to do alone, I wish to have a partner in this one, because I am clumsy and therefore afraid of traffic and lost the direction or any unpredictable events which usually happens only to people like me. Anyone?

to do it in September

Planned time: 8 hours
Planned kilometers: 112 km
