I cycle from the Atlantic seaboard to Paarden Eiland (to the same gym) 3-4 afternoons/evenings a week, via the harbour. I've got membership at the RCYC -- R1.7k pa for my age -- pretty much just for the harbour access.
It's a privilege to be able to brave the wind far from traffic and dodgies, but it's a shambles to have to avoid the cycle lane to commute safely. Would love to get involved!
