There isn't a typical trip, but if there were it might be... On Tuesday / Wednesday you would be checking the surf forecasts and considering where to go, liaising with club members and come Friday meeting at the rendezvous, say at Hammersmith tube.
You'd pile into the car drive down to Devon / Cornwall, arrive late, sleep in the car, tent, hostel or B&B depending on the time of year and who you're with.
Saturday, you'd surf, have brekkie, surf, lunch, surf, evening meal, pub, club or early night. You'd repeat the process on Sunday getting back in time for last tube or door to door service depending on who you're with.
