Hi there I did the 30km last year and wasnt very fit and had to walk the mamba.This year Im doing the 80km and last weekend we went for a practise ride. I can tell you that I only walked 200m on mamba hill and Im rideding a mtb. Hope you will enjoy it and Im sure that mamba wont be that difficult for you. The ending is on mamba hill and then you have to ride 4km to the event were we started but ist downhill then.
