Definition: Tapering is the training phase right before a long distance event, such as a marathon, when a runner starts to cut back on his or her mileage. Marathoners typically start tapering 2-3 weeks before their race. This reduced training phase gives runners a chance to rest, recover, and mentally prepare for their race.
