If you still haven't made plans for Christmas Day we've a few last minute suggestions for you.
Join the Serpentine swim: as we saw the other day, there's nowt as refreshing as a mid-winter dip. The Peter Pan Christmas Race has been held at the Serpentine Lido since 1864. You won't be allowed to swim unless you're a member but we can vouch for spectating being excellent fun and will mean a brisk walk through wonderful Hyde Park early in the morning. The race starts prompt at 9am so if you're planning to go, get up early - there isn't any public transport all day!
Cycle Southwark: Keeping in the outdoor sport vibe, Southwark Cyclists are running a slow and sociable ride round deserted Christmas London. Meet 10am at Cutty Sark Gardens or 11am at Southwark Needle. It's brilliantly laid back: it's free, no need to book, just show up. Linger for a late lunch up Edgware Road after and hang about for the evening's Critical Mass ride from 6.30pm.
Test your credulity: Ripley's Believe It Or Not is open on Christmas Day between 10am-8pm. For the skinny, read our interview with the Odditorium founder. They've also got a hot tip for Christmas dinner - believe it or not: the Turducken.
Walk in Pepys & Dickens' footsteps: London Walks are running 2 tours. "Christmas Morning, 1660 - Samuel Pepys's London" goes at 11 am followed by "The Christmas Day Charles Dickens's London" Walk at 2 pm. Meet at the big Christmas Tree in Trafalgar Square. £7/under 15s free, no need to book.
Whatever you do, Christmas Day in London is pretty special. We also recommend photographing the unpeopled city, visiting your local park for a stroll and saying hello to strangers. Enjoy.
