So me and my friend thought that would be an awesome experience to hike Mount Whitney at the end of June. Although the more I read about it, the less sure about that we can make it one day.

We both in our late twenties, in good shape. We both have long day hiking experience. And I think I can safely say that the same trail on normal altitude wouldn't be a problem for us.

We would arrive early the day before the hike and do a practice hike to lone pine lakes. Rest and try to get used to the high altitude a bit. We would prepare with Diamox / Ibuprofen and drink a lot of water all the way. I know that we'd have better chances with longer acclimatization, but unfortunately we won't have more time to spend in the sierra. (Maybe next year ;))

We'd start around 1:00am with tracking poles and light backpacks.

What do you think, what are the chances of making a successful day hike?
