Route from Barrydale to JHB- suggestions please

[Frog]

I'm planning a solo bike trip (unless someone wants to join me) from Barrydale up to JHB. I will be leaving Barrydale on the 28 September and would want to spend 3 to 5 days on the road exploring the country. I will be doing some homework on a possible route but any suggestions or advise would be appreciated
