Climb the 3 peaks of Table
The 3 peaks of Table Mountain are Devils Peak, Table Mountain and Lions Head. Climbing all 3 in one day is a challenge but a little bit more practical than the 3 peaks of the UK as there is no driving required between peaks.
There are a couple of organised races up the 3 peaks. The most gruelling of these requires runners/hikers/plodders to return to Green Market square in the centre of Cape Town between each Peak. This adds a distance of about 30km onto the challenge.
To do the 3 peaks merely returning to Tafelberg Rd each time is a distance of +/- 27km (depending on your route) The peaks can be bagged in any order but generally people aim for Devils Peak, Table Mountain and finally Lions Head.
