yes it is suitable as a training run, having done a few times I just clocked the miles off at the desired pace. doing four laps can be a pain but it good, to break it up into say 4 by 45 min loops and work on your pace.
looks like it is runners world race of the week.
Any one running this race this year?
Good Concise Review.
