ChicknNuggets - I didn't. After many, many hours of creeping towards Pietermaritzburg, they turned around and went back to Durban. Of course I did not know this, and wandered around the International tent looking for them without success. I had no phone, but I found Slow Duck who kindly allowed me to use his phone. I think they can make it if they go directly there around 10 am - i.e. after the buses have dropped all the runners off.
ChicknNuggets - it is a nightmare getting to the finish on the Up run. The traffic is so intense that unless they go straight there first thing in the morning, they will not make it. Any stops to see you en route will derail the plan. My family - who are local and know the roads well - could not get to the finish.
