you can keep a type of keto but it will more of a timed carb diet, most of the carbs should be during/after working out, then take the rest and use it for the day. Now I know that doing KB work and trying to take a sip of a carb drink can almost make you throw up so I don't recomend taking drinks durring the workout too much.. just very very small sips.
if you have a 40-50 carb drink after working out and some bcaa that would aid in repar and keep you going then have pro/carb/fat meals the rest of the day. this way you have moderate carbs throughout the day and most of the carbs when you need it.
Let us know how every thing works out.
