Hello,
Will be going to Yosemite June 1-3rd, and am planning on running/hiking to the top of Half Dome from the trail head around 3am in order to make it to the top for the sunrise. Wondering if anyone has done this and has any pointers, and if there are any runners that would be up for this? I've spoke to a few trail runner friends that have done this and they think it will take about 2.5 hours.
If anyone has done this trail at pre-dawn, are there quite a few hikers out at this time?
Thanks!
