But seriously it's typical for beginners. Your muscles are just weak and you fire up fast twitch fibers at low speeds (relative to your vo2max) so you obviously experience fatigue fast.
That is very interesting. Can you expound on that? I did sprints for a long time (swimmer), and now that I do endurance training, I wonder how much fast twitch muscle I use for long distance tasks. In maximum efforts, doesn’t the body call on slow twitch fibers first?
