Power hours, vertical miles, or similar events are multi-lap races of an hour or more. In this document, we will be using hour as the time limit or description in several places, although the document generally applies to longer or shorter races of the same format.
A power hour is a series of climbs in a staircase, usually descending by the elevator. Every trip up counts as one lap. Typically, the goal of a power hour is to complete as many laps of the building as possible in an hour. A power hour is differentiated from other multiclimb races by the fact that the goal of the competitors is to climb the staircase as many times as possible during a fixed period of time, usually an hour. The goal of other multiclimb events may be to climb the stairwell a certain number of times in a given time period.
Tie breaking is done by lowest time in the staircase. If two climbers complete the same number of laps, but A completes the laps in 48:50 and B completes them in 52:12, A places ahead of B in the ranking. They will both finish higher than any climber who completes only six laps, no matter how quickly those six laps are completed.
Power hours and multiclimb events still have staggered starts; one person is sent up in short intervals to start the race. After the first lap, the racers descend the elevator and enter the staircase as fast as they can. Racers returning from the top should not be impeded in any way from re-entering the staircase to ascend again. There is no staggering at this point, and racers starting their first lap should wait for racers who are starting their subsequent laps.
A power hour doesn’t end at the same time for each racer. A racer’s clock starts when they first enter the staircase. Their hour ends when an hour has passed since they began their first lap. As long as a lap is started inside the racer’s hour, the entire lap counts. If a climber begins her first lap at 7:05 and she completes 7 laps in 58 minutes, she returns to the start at 8:03. As long as she enters the staircase before 8:05, she will be able to start and complete one additional lap, and her race total will reflect that. It doesn’t matter how far after her hour ends that this lap ends, just that it starts in time. However, she is still incentivized to climb quickly to achieve a lower overall time which could greatly affect her ranking, as many climbers may achieve 8 laps that day.
All the typical stair climb etiquette with regards to passing and impeding apply to power hours and multiclimb events.
