Ten weeks to the top of the CN Tower

This blog was updated on March 6, 2023.

Every year, thousands of people of all fitness levels ascend the CN Tower to raise funds for wildlife. The average climber reaches the top in 30-40 minutes. Whether you’ve never climbed or are looking to shave minutes off your time, WWF CN Tower climb record holder Shaun Stephens-Whale – at 9 minutes, 54.9 seconds – recommends this 10-week training program to help you reach your climb goals.

Register and start training now for WWF’s CN Tower Climb this April 15 and 16.

Some tips before you get started:

• Set a realistic race-pace goal (this is the time you want to take to reach the top). The CN Tower’s 1,776 steps are equivalent to about 100 floors in most buildings. So, if your race pace is 30 minutes, train to complete 10 floors in 3 minutes.
• Always warm up before training and don’t forget to cool down.
• For stair workouts, it’s best if you have access to a building with at least 20 floors. If you don’t, the stepper at the gym is a great substitute.
• If you plan to take the CN Tower steps two at a time, incorporate a combination of double and single steps into you training.
• One final piece of advice: If possible, take the elevator back down.
