Depending on your current size, i'd be looking at something like 2 miles, 2-3x per week - that should not be excessive. A key issue to be aware of whilst running is core stability - for the most part it will be the cause of the majority of running injuries, mainly arising from bad posture/stride.
As you get comfortable with a given distance, just build things up slowly, don't rush or expect to run a marathon in 6 months. |
