Isn't there a device currently on the market that restricts your breathing for you...
It seemed quite clever the last time I had a look.
Me and the gf have signed up for a marathon and half marathon respectively at the end of the year.
I just bought her some new running shoes (she's a much better runner than I am) as our anniversary present.
Training from a 10k base will start at the end of March.
