Back for 2015, this event is a must for all bike, sport, travel and outside enthusiasts with plenty of information, shopping opportunities, guest speakers and family-friendly have-a-go experiences. This year sees WhaleFest London join the lineup, a pop-up which boasts life-sized replica whales and an indoor whale watching experience, giving insight into just how clever these creatures really are. Climbing plays a major part in the day's lineup so it's only fitting that a new climbing wall has been developed for the event, and a brand new obstacle course created to test visitors limits installed. Expect monkey bars, huge walls and rope climbs. Those keen on exhilarating heights will also want to try the world's longest indoor zip wire. Returning attractions include the 'On the Water' zone for lovers of sailing, kayaking and surfing, as well as 'The Telegraph Travel Stage' where visitors can gain advice and discover the world's hidden gems from travel experts. Your ticket will also give you access to the Bike Show, which features pro-riding displays including aerial stunts plus a test track where you can try out the latest models, as well as the Triathlon Show London, and the London International Dive Show. Children under 8 get in for free but still require a ticket, group and advance discounts are available. See the show's website for a full list of exhibitors, activities and talk times.
