4am - Depart Trail Camp, VERY difficult from this point on (past Trail Crest, I felt like I had to stop every 10 steps!), snail-pace at ~1mi/hr LOL
9am - Summit
You had Mountaineer's Foot - can't put one in front of the other.
In all due respects, the reason it took 5 hours was probably lack of any or full acclimatization. Same reason for many of those folks who do not get to the top at all.
I am 63, never do any prep but 1 hr walks in lowland VA. After sufficient time up high, I and have done that stretch (including one week ago) from either side 12,000 ft level (Trail Camp or Guitar Lake to summit) in 3 hrs. If it took you 5, there was a problem. Yes, it may have been simple fatigue, but lack of acclimatization seems very likely. You would be amazed at the difference if you ever go back and do it with more days of pre-acclimatization. Someone will chime in about Diamox that helps a little, but the key is time, time, time. More nights first at higher sleeping altitude.
