That's a pity that you don't see them anymore in that area... Why do think that is? you say not even breakfast runs anymore...? Do you think it became too risky with all the cattle down along the N2 route?
Yes, that would be interesting to know who started the event! I'm so glad you like the 'Ghost Rider' image👍!
They no longer use the R603 as much as they used to on breakfast runs. Further down perhaps road conditions or they leave at different times, not the large runs that you would hear them from a distance. Roads not always great either with potholes.
The South African Toy Run was started by BikePoint contributor Steve Kealy and his wife Liz 26 years ago, in spite and in violation of apartheid laws of the day. Source
Now in every large town and city throughout the country where there are bike clubs arranging local event end November each year. Also being adopted to be held in Australia according to the link above.
