depends on what you are used to, what event you are training for and how fast you are planning on doing this etc…
Work of any sort is best when spread out over the week.
Are you doing this to save time?
Have you read any of the training materials from this site?
As a back ground to what the top track athletes in the world typically do reading Speed Trap is a quick read with an overview of how to train.
hope this helps.

btw, experienced athletes who require larger amounts of tempo for their event have done 2 sets of big circuit with 5 to 10 minute break.
I’d like to know what kind of time you are running this in for one Big Circuit before understanding how much tempo in one session.
