If you think the Arc de Triomphe at 284 steps in Paris is a hike, the Belfry of Bruges is 366 steps.
The StairMaster machine caught my eye on a recent trip to the gym. The next day I researched step counts of the belfry and a few other attractions from my past travels. That night I simulated the climb up all 366 stairs. It took me 8 minutes, it was brutal.
