My advice for long runs

Don't try to run 15 miles in 90 degree weather! :) I'm sure anyone reading this is smarter than me and would not do this anyway, so this advice is to myself. As someone who is prone to heat exhaustion and who has been dehydrated on runs before, you would think I would have learned by now!! Luckily I have learned the signs of dehydration, for me, chills, nausea, and a very strong craving for salt! So I did not risk it further and ended up walking most of the last three miles. So I am fine, just a little frustrated with myself! I am a slow learner sometimes!
