The London Marathon is not the only endurance game in town. Louise Schwartzkoff searches the city for other activities that take strength, stamina and competitive zeal.
Knockout Speed Dating: Putney
Okay, so this does involve exercise, but with the added incentive of potential romance. Turn the hard work of speed dating into a hard workout by going toe-to-toe with hopeful singles in the boxing ring. After slogging it out, chat up your favourite sparring partner over drinks and healthy snacks. They say all's fair in love and war. That's doubtless truer than ever when love blooms in the ring. St Mary's Church. Putney Bridge. Mon Apr 25. £20.
The Homebaked Bake Off Battle: Baker Street
Skilled competitors, gut-clenching suspense, the elation of victory and the misery of defeat. As a spectator sport, baking competitions have it all. Bakers will bring their sweetest showstoppers, appropriately enough, to Baker St to be judged on taste and looks. There'll be masterclasses from champion bakers and treats to try. Ready, set, bake! Sherlock Holmes Hotel. Baker St. Sat Apr 23. Free.
Movie marathons: Leicester Square
Grab your jim-jams and ingest caffeine liberally before settling in for an all-nighter at the Prince Charles Cinema. The independent West End venue was once famous for screening porn, but the programme has moved from sleaze to a blend of new-ish blockbusters, arthouse titles, horror, sci-fi and more. This weekend's marathons include back-to-back 'Hunger Games' and a celebration of films by Edgar Wright, from 'A Fistful of Fingers' to 'Shaun of the Dead'. As you stumble, bleary-eyed, to buy popcorn, keep an eye out for the ghost rumoured to haunt the upper levels. The Prince Charles Cinema. Leicester Square. Sat Apr 23. £20.
Food challenges: Hoxton Square
Is there really any difference between runners who push themselves to exhaustion and the iron-gutted heroes who participate in Meat Liquor's Triple Chilli Challenge? Let's face it, both groups end up sweaty and a little bit sick, but bathed in ever-lasting glory. The burger joint's challenge is simple: ten minutes to scoff a burger, hot dog and fries, all packed with fiery mouthfuls of chilli and jalapenos. Can't stand the heat? Try Red Dog Saloon's Devastator Burger Challenge: ten minutes, one milkshake, a serve of fries and a burger the size of a man's head. Only 7 per cent of those who compete succeed. Meat Liquor. 74 Welbeck St, W1G 0BA. Bond St. Red Dog Saloon. 37 Hoxton Square, N1 6NN. Old St.
