Running

Do you carry water/fuel while running? 

If so, do you prefer a hydration vest/backpack or a handheld bottle?

i usually run 10kms and i dont carry any sort of hydration.

I've noticed that if i'm out for longer than 120mins water or fluids is key.

If the prescribed workout is under 90mins ill usually go without.

totally agree.
i usually run early in the morning, with cold weather. 

i have had runs in places with high humidity/temperature where fluids are key even im running less than 90 mins, specially if theres a lot of humidity.

I'm typically a morning runner, and being in Southern California, we don't experience much humidity here.
