The"train"way or the"highway"?
 

Hello everybody,
I'll be riding solo from Lisbon to Dakar,time
permiting Bissau,nxt January and really could
use some advice on which route to plan to get to Nouakchott;
Is it really complicated and time consuming
to get that train to Choûm,up to make you spend an entire day in Nouâdhibou?
is it ,on the other hand,unwise for such a low experienced offroad biker like my self to follow the railways to Choûm/Atar?
or should I try riding along the beach ,keepin' an eye on the tides?what sort of terrain is that on the "beach"?
or should I just trust and follow the "semi"Highway about which I don´t know much but seems to be the easiest and fastest way south?
and by the way ,any GPS coord's to those options...?

Would really love to hear from you veterans out there!
Thankin'you all in advance,

nice rides.
