Dont Stress About Healthy Habits Over Holidays the New York City Marathon, researchers began to track the runs of 735 participants, ages 18 and older, to analyze changes in their training volume and injury status. During the study, runners tracked their mileage through Strava and completed a survey every four weeks to report any illnesses or injuries that interrupted their training or resulted in them not competing.
“There’s a lot of different ways that you can look at training in terms of mileage, pace, frequency, and heart rate. What we wanted to do is start with something that is relatable to runners because runners often discuss their training in the form of mileage,” lead researcher, Brett Toresdahl, M.D., attending physician at the Hospital of Special Surgery (HSS) and research director for the HSS Primary Sports Medicine Service tells Runner’s World.
For the purpose of this study, training volume was analyzed using two common methods: The 10-percent rule and Master the Half (ACWR). The 10-percent rule recommends runners consistently increase their training volume by no more than 10 percent each week. A more conservative approach, Toresdahl says this isn’t always an ideal way to increase mileage while For the purpose of this study, training volume was analyzed using two common methods: The. The ACWR method, on the other hand, is used to compare weekly training volume to monthly training volume. For example, Toresdahl explains, if you ran 20 miles in the past week but only averaged 10 miles in the past month, your ACWR would be 2:1 or 2.
In the end, researchers found a link between runners who had an ACWR of 1.5 or more and injury, while there was no association between injury and exceeding the 10-percent rule. Runners who initially reported injury during the first month had more days when their ACWR rapidly increased than those who ran injury-free that month.
“If your training volume in the past week was 50 percent higher than the average of your training volume over the past four weeks, that would be a risk factor for injury,” says Toresdahl. (That means if you run a weekly total of 25 miles this week, your previous four-week average should be somewhere above about 17 miles.)
That doesn’t mean everyone who exceeds that amount will experience an injury, but rather the more times you exceed that amount over the course of training, the more likely you are to become injured, Toresdahl says.

Meaning, there are plenty of ways to approach safely increasing your mileage to remain injury-free as you train for a marathon—the key is listening to your body and not doing too much too soon.
