There are several MTB and road cycling routes, some of which include segments of the famous Cape Town Cycle Tour, the largest timed cycle race in the world.
The Red Hill MTB route is an intermediate MTB route nearby. You can ride from the house down Kommetjie Road and up the Glencairn Expressway before turning right onto the MTB route at the top of the hill. Or drive there. Check out the single track along the western side of the Glencairn Expressway, a short bermed downhill route with butt-clenching table-tops, jumps and huge drops.
For a more gentle road ride, head through the village and head south along the coast up the hill past the lighthouse and down to Scarborough. The return trip is almost 20km.
For a longer workout, head to Cape Point and down Smitswinkel, through Simonstown, and left up Glencairn Expressway to Kommetjie via Sun Valley for a 50km loop.
