Brooks Running conducted an online survey of 1,000 runners called the Brooks Run Happy Nation Report . Among its conclusions was that 66 percent of runners believe they have more sex when they run with their significant other. Not only that, but “The longer you run the better your sex life, the survey found, as nearly half (49 percent) of couples who run six or more miles together claim it pays dividends in the bedroom.”
This seems self-evident to me. A sprint can be exciting, but it’s a lot more gratifying when you cover a lot of ground with a slow, gradual and steady pace.
