gravitational potential energy?

Assume my equipment and I have a combined mass of 115 kg. And I go for a hike starting at Yosemite Valley (elevation = 1219 meters) and I walk up to the top of Half Dome (elevation = 2694 meters). What is my change in gravitational potential energy? If this hike-climb takes 7 hours, what is my average power output?

Gravitational potential energy = m*g*h
This will be in Joules

One watt of power is 1 Joule/sec

P = m*g*h/t
