Well, it's definitely not as flat as Eldron describes

;D
Although there aren't any roads which have real hills. There are some places around the residential areas that have very steep short hills but otherwise nothing more than steep drags. What we do is hammer those drags hard at about 45km/h and then it feels a real hill. ;D
Best thing to do when you arrive is to make a visit to Finish Line Cycles in the Glen Acres shopping centre. Speak to Clint about training rides and cycle route and check out one of the most affordable bike shops in Joburg (the other being Westdene Cycles).
BTW, Kempton Park has produced some of the best cyclists in the country
besides myself of course. LOL
