Twickenham will be hit by an influx of superheroes this weekend. Why? Well, it’s the London 7s rugby tournament. Eh? Sevens is short, fast-paced, 7-a-side rugby played on a full size pitch. With teams coming from across the world, “what’s not to like?” as irritating people increasingly say. Why superheroes? Well, the event, which is sponsored by Emirates air (plug, plug) is pushing that theme. Turn up dressed as one and you’ll help create one big party. It might be worth a visit regardless of whether you can still squeeze into the Wonderwoman outfit that you last wore for Charlie’s stag/hen do back in 1997. Tickets are cheap (only £5 for kids) which makes it an affordable proposition even if you don’t stay the distance.
