This plan is built on a 9 day cycle, which means you will have a long run every 9-10 days. This plan will build up to 55 miles/week at peak. It starts at 5 days of week per running and will finish at 6 days per week. The first few weeks are base building (assuming you are coming off a break), and these weeks can be take off if you need a 14-16 week schedule. The plan comes with a structured workout feature and day to day pace guidance based on your goal time.
