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.
Generally, it takes a minimum of two to three weeks for the body to recover from the strain of running 26 miles 385 yards. Return too quickly and you increase your risk of injury. Some experts suggest resting one day for every mile you run in the marathon, thus 26 days of no hard running or racing!Others suggest one day for every kilometer, thus 42 days rest. Well, that might be waiting too long before resuming tough training.eturn too quickly and you increase your risk of injury.
