I use smartcoach for all my training plans as I like the way it ramps up my distance and gets the tempo speedwork balance right in the build up.
However I find some of the pacing from smartcoach a little baffling and have never found an explanation of what it is building you up for (PB? Same as before?) so I have taken to modifying it a little. I always enter my PB for that distance instead of the last race like it asks and the long and easy runs I find the suggested pace a little to far off my target so I tweak a little faster.
Maybe I should have more confidence in what it says but I have never followed it exactly and has been ok so far. I know this is not answering your question but maybe try mixing it up a little. It really depends on how you have recovered from your injury on what pace you can acheive.
Never understand why people pay for pics. I always look a wreck in them so certainly would not pay anything to look at that. In my mind I look like Seb Coe sprinting to the line so I tend to stick with that than the reality,
As they give out bottles you should be fine to use theirs as you can carry the bottle for a few k and take on all you need. Smaller runs that give cups are a pain and I prefer to carry my own. However as book said if you want it then do it.
Start to analyse how much water you are consuming in training. I am always sceptical on whether runners really need the volume provided in a camelbak (depending on distance of course).
I think the great runs give out powerade at half way which I advise (if you are going to use it) then train with it first. It did not agree with me at all.
Last piece of hydration advice form me is to have some flat cola in your kit for after. You can stick your power drinks flat cola is the only way to go just dont guzzle it.
