Something to consider for others who might read this post: If you are a runner and training to run a long race (marathon or the sort) and you know the race will be in the morning, it might make sense to do a lot of runs in the morning. Ideally you run about the same time you race for two reasons: 1) Getting used to running that time of day can be important. It'll be good to get your body/mind used to running hard in the AM if you are not used to it. 2) Bathroom habits can be training/learned. If you get up and run each day at the same time you can eventually 'learn' to go to the bathroom before your run. Could save you a few minutes race day if you have already taken a 'pit stop' before the race is underway.
This can also be applied to multi-day running. If you will race through the night, it will be wise to train your body (and know what it feels like) to run at 'weird hours'.
Otherwise I agree with the above, as long as you have good time for recovery, anytime will suffice for training.
