I believe you're in the wrong forum for this, but I'll answer anyway and Steve may move this thread.
Let's start by getting a clearer picture of your goal. 40 minute maximal test I am to assume means that you are going for maximum distance?
Please let me also add that I am not anywhere close to an expert in endurance events. I do know, however, that many of the top endurance athletes in general do 75-80% or more of their time in Zone 2/MAF 180-age type of effort level. The goal over the long term here is to slowly build this pace, while maintaining the same HR/effort level. Your steady state, LED or LSD sessions as these are known would qualify here.
The other amount of time endurance athletes do sessions such as be tempo, fartlek, intervals, etc. The point of any of these is to challenge yourself at a higher pace, allowing optimal recovery. I'm no expert at any of these as I don't work much with endurance athletes.
Anti-glycolytic means pushing the alactic system to the brink, but allowing sufficient recovery. "Repeats" are preferred to intervals; whereas intervals we expect a slow decline in output, repeats we want to match output each time. Of course, due to many reasons you can't sustain this forever, and you will lose output but at a much longer time frame compared to an interval workout.
You have listed a "hard" workout, yes. It is very likely glycolytic; that would be confirmed by doing it, but my guess is you would not sustain that for more than 15-20 minutes without pushing over the edge, making it not a good example of "repeat" efforts.
I'm going to leave specific suggestions for others with more experience and watch this thread for info!
