If you’re looking to do a marathon or 1/2 marathon in the next 6 months I’d highly recommend following Brian Mackenzie and his Crossfit endurance running training program – With slight adjustments to the workouts to be bootcamp classes/ personal training, this program will drastically increase your ability to run and your efficiency, strength and speed!
Check out his 12 week training program here http://running.competitor.com/2011/05/training/brian-mackenzies-12-week-crossfit-endurance-advanced-training-program_28400
