Once back, I donned the wetsuit and joined the official practice swim on the beach with a few hundred others. The sea was beautifully calm, but full of jellyfish! I am no great fan but I have come to accept them as a necessary evil, although one guy I spoke to was less enthused and had taken to breast stroking to avoid ducking below the surface! In my own mind I told myself that the jellyfish were a worthwhile inconvenience if the sea could just be as calm on Sunday at 7am!
