Good work, Martin. This is the way to go - doing the actual work instead of just talking about it (as some people tend to do). Anyway, as someone here said - rest a lot between the workouts. Do not rush the progress.



I am not an expert but I would advise you to just keep at what you are doing now - jogging + fast walking. Gradually your endurance will get better. I would take it slowly. There is no need for any shortcuts that may work for a short amount of time but can wreck your health in the long term. I have read a story about one runner where rapid training from zero took its toll (not exactly a small one).
