Art13 London at Olympia

Billed as ‘the most exciting new art fair launch in a decade’, Art13 - organised by the people behind Art HK – will bring 129 international art galleries under the same roof in Olympia’s Grand Hall. Thousands of artworks, including painting, photography, sculpture and prints, will be on display and prices start from just £100. For those wishing to make a day of it, the exclusive Fortnum and Mason Champagne Bar & Restaurant should be a delightful place for a spot of afternoon tea. Get two-for-one tickets to Art13. 1-3 Mar

The Wine March

If there was ever a good excuse to drink wine, this is it. Raising money to build water projects in poverty-stricken areas of the developing world, the 2Water Wine March is a five mile walk along the Thames, with stops for wine tasting along the way. Led by the Three Wine Men – TV wine experts Oz Clark, Olly Smith and Tim Atkin MW – the march starts with a glass of wine at Vinopolis, before heading east via Gordon Ramsay’s The Narrow to Canary Wharf gastropub The Gun. Tickets are £15 and include a glass of wine at each stop, with all proceeds going to the 2Water charity. 3 Mar

Angela Williams – An Hour with Audrey Hepburn at the Heartbreak Gallery

Head to the aptly named Heartbreak Gallery to see stunning photographs of Audrey Hepburn, many of which are on display for the first time. Taken at the Ritz in 1964, the photographs capture the actress’s innate glamour, charisma and beauty, and are sure to have you longing for a bygone era. Follow this with a look at Williams’ snaps of other 60s icons, displayed in the adjoining room. Entry is free. 27 Feb – 31 Mar
