> What is curious to me is that elite marathon runners "jog" at what I would consider being a sprint for myself. So, I wonder if sprinting would be an anaerobic or aerobic exercise for myself?

Everyone has an anaerobic threshold (the level of exertion at which the body transitions from aerobic to anaerobic systems).[0] But your AnT is much, much lower than an elite marathon runner's due to years of training designed to increase running economy.[1]

So what is a sprint to you (e.g. anaerobic exercise) would be a jog to Kipchoge or Bekele (e.g. aerobic exercise). If you are able to run fast enough to make yourself gasp for air, you've just done some aerobic exercise!
