I was thinking of interval training as a separate session lasting about 20-30 minutes long and dedicated strictly to max efforts repeated for several sets with set amount of rest in between.
Having 1-2 max efforts scattered far and between on a 2-3 hour ride or a longer distance ride isn't interval training. Sure you can still get some benefit from it but it's not really a dedicated interval training

But what happens if he doesn't go to failure and stops at a borderline between aerobic and anaerobic zone, would you still consider that to be an interval training ??
