Four hundred and fifty vehicles, all built before 1905, will take part in this annual 57-mile run (above) to the coast to commemorate Emancipation Day, when a man with a red flag or a lamp no longer had to preceed all vehicles.
At Hyde Park there will be pre-run festivities or you can join the crowds lining the route - over Westminster Bridge and along the A23 to Croydon - or you can check out "younger" vintage cars in the East Piazza at Covent Garden (9am-12noon).
London Aquarium, County Hall, SE1 (0171-967 8000) today and tomorrow, 10am-6pm, pounds 7 adults, pounds 5 children
Yet more Hallowe'en jinks with special appearances (and disappearances) by Count Dracula, ghosts, skeletons and zombies at this award-winning aquarium, where children will be given free Hamley's goodie bags. What the fish will make of it is anyone's guess!
Dolls House Fair & Teddy Bear Fair
Alexandra Palace, N22 (01903 244900) today and tomorrow, 10am-5pm, pounds 5 adults, pounds 3.50 children
No ghosts and ghouls here, just hundreds of dolls and doll's-houses and teddy bears. Saturday is Collectors' Day for serious enthusiasts, Sunday is more suitable for children, say the organisers. Free courtesy bus from Wood Green Tube and Alexandra Palace BR.

There's also the usual children's attractions, such as the water maze and adventure playground. Activities are held indoors, so it's a good option even if it's raining.
Spooky Stories and Songs
Old Sarum Castle, near Salisbury (01722 335398) today and tomorrow, 12noon- 3pm, pounds 2 adults, pounds 1 children
This Iron Age hill fort is a suitably mystic setting for Hallowe'en tales from "Emerald the Witch", who will sit in a creepy "cavern" and tell stories and sing songs. NSReuse content
