As I promised, I am posting some information about calculating Power Output for the stair climb. As a reminder, here is a link to a previous post regarding some Power Outputs for stair training sessions.
P = (BW x 310 x 1.3558)/T
- P = power in unit of measurement "Watts"
- BW= climber's weight in pounds
- 310= height of total displacement in feet (event-specific)
- 1.3558 = adjustment to Watts from ft-lbs/sec
- T= climber's time in seconds
So my wattage for the 4:52 was.....342 Watts! Compared to training sessions, this was high. The highest attained wattage during training was only 178 Watts, about half of the intensity of the actual competition. I guess I need to make some adjustments to training next year! I can make the adjustments by doing more work in a taller building, thereby decreasing "down" time....pun not intended.
If you calculate your own Power Output, be sure to post in a comment.

My Power output was a meager 208.36Definately room for improvement
307.5, if I did it right, I know I could of pushed myself a little more
This is a good formula, thanks.
If you're doing sets of stair climbs with jogging down in between, do you give yourself 0 wattage for the rest period? I know it's not as hard as the way up, but I am still doing some work.
I used this calculator to get the total joules for my workout which included other movements:

P.S. This post doesn't have a "stairs" tag.
Where did you get the 310 number from?
The race has 664 stairs, each with 7 inches of rise.
(7 x 664 / 12 )= 387 vertical feet.
UPDATED: 422 Watts with height of 387ft. Thanks to whoever measured this!
