That's quite a bit of determination you have there. 5 hours and probably over sixty pounds of bike + backpack + water or whatever else you took with you.
Since I had no prior experience on slopes any more than a ¾ mile long or so, I was fearing that I too would be struggling for 4 to 5 hours. Luckily I only had about 20 pounds or so to go up the mountain with.
