Sorry, but I just have to say this once and for all in really plain language. In 4 years time Mike wants to race with the very best athletes in the world, the upper echelon. Maybe even to make Mo Farah redundant. He's been training for a month of two now and feels quite good about it and is pleased by his improvements.
NO BL**DY WAY is it going to happen. Sorry. 
How long to get fit enough to compete at elite levels? How long to impress selectors with your racecraft and prove yourself in major tournaments across the world? They don't give out Olympic places in 5,000metres and 10,000 metres to people with potential. They give them to proven winners.
Sorry Mike, unless you start talking about the Olympics in Istanbul 2020, you haven't got a hope. The goal you have in your head is WAY more difficult than you comprehend. If you had more time, perhaps you could do it. But talk of Rio is utter nonsense. Stop making a monkey of yourself, join an AC and start working hard. Come back to this thread in a year's time and then tell us what your ambitions are, because right now, you don't know what you are talking about. And you blithley ignore the people that do have a bit of a clue...
It might sound harsh, but it's the same when kids find out that Father Christmas is a fairy tale. However, it is healthy to understand what is real and what is not. Good luck fella, but get real. Please.
