I think the short intervals (100m) will not cuas emuch of the adaptations you ar elooking for (increased mitochondrial density, increased glycolytic and oxidative enzyes etc). That said, if you find a comfortable level you can chug along for quite a just have ot remain below the level of substrate exaustion. Even a few 200-400m repeats (long rest between bouts) will force the adaptations you are looking for. Good economics on this: Minimum input, max output.

Silly Science!
