By Christine Hinton June 22 2015. Weâll take you from the couch to finishing a 5K in less than two monthsâand a half marathon in just 14 weeks.ouâll start out with 3 miles and build from there. Every few weeks this distance will drop to allow your body time to recover. The long workout will be vital to teaching your body how to spend time on your feet, utilize fat as an energy source and simulate the half-marathon distance.
Keep in mind that the Nashville Marathon requires you to complete the half marathon within 4 hours and the full in 7 hours.
