The Triathlon Show
Time Out says
Returning for 2016, this show offers both new and experienced triathletes a plethora of activities, information, kit innovations and advice from experts and professionals. Visitors to the show can use the wetsuit testing pool, take a Swim for Tri masterclass, use the cycling test track and pore over the wares of more than 140 exhibitors displaying and retailing the latest swim, cycle and running kit.
Children under eight get in for free but still require a ticket, group and advance discounts are available. Tickets also allow access to The London Bike Show and The Telegraph Outdoor Adventure and Travel Show, which take place on the same weekend.
