Today was 2.75@2i, 5x(.25@6:22+.25@8)+.25@6:22.
Some people swear by Camelbaks, others prefer a hydration vest (same concept, less backpack style), others like Fuel Belts, and still others just stash water on their route. I'm not a big fan of my Camelback for running, I find it bounces a bit too much, and I run way too hot to use a vest, even in cold temps. Normally I'll use a Fuel Belt, or stash a bottle on my run, depends on where I am going and how long. I just can't bring myself to drink more than I can carry in the Fuel Belt, even on 20+ mile training runs, so I don't bother with anything larger. Stick a few bucks in a pocket somewhere and know where a convenience store is if something goes terribly wrong and you need more water.
Just plan on slowing down if it's hot out. Sunglasses, sunblock and maybe a hat are key. Go as early/late as you possibly can, maybe even grab a headlamp/reflective vest and go when it is still dark out. But if it's going to be that hot and I need to do a long run, treadmill it is. 80+ I will usually max out at 10-13 miles outside, anything longer will be at the gym.
Thanks @dreamfinder for the advice. I've got a Flipbelt I wear for runs outside my neighborhood since it can hold my phone, keys and ID (hate the band around my arm) and they make small bottles that fit in the slots, so I will have to pick up one of those. Since I live in Florida - the land of mosquitos - I want to avoid running at dusk or in the evenings as much as possible. And you're right, there's always that boring run on the gym treadmill.....
Don't think I'll be doing 20+ mile training runs, like you. I'll be happy if I can finish the one 14 mile training run Galloway has in his program for halfs without rolling over and dying.
