In celebration of their 20th anniversary, Flight Centre Canada is giving away 20 round-trip flights to London, England — but they’re going to make you work for it. On September 22, 2015, the travel retailer has designed an all-day sight seeing event they’re dubbing We Love London Ticket Race, that will take participants on a whirlwind hunt around Toronto for a shot at one of the flights.

Anyone (who can sneak away from work) can join this Amazing Race-style adventure. Between 9am – 5pm Flight Centre Canada will be sharing location clues through social media every hour that will point you to key locations in Toronto created as iconic London experiences. Here you get a chance to test your London know-how against Flight Centre Canada’s Airfare Experts at each checkpoint, where you can earn “boarding passes” that will give you access to the exclusive after-party. The key to winning the flight? You must be the first participant to arrive at each checkpoint with the secret word (revealed on social media).

Didn’t make it first? Don’t fret. There will be a London-themed after-party at a secret pub location announced on social media just a few hours prior to the start. All “boarding pass” holders can enjoy British themed snacks and pints. Plus you’ll also qualify for one final chance to win two round-trip flights to London.

Not in Toronto or can’t take a (cough, cough) sick day? There will be an exclusive promotion on select Air Canada Toronto-London flights on September 22.
