The old 10% rule doesn’t hold up any more unfortunately, if you are looking to increase your Weekly Mileage and aiming for longer running races then don’t leave it to chance and continue reading.
In every Physiotherapy Clinic in the world, the injured runner presents with an increase in something…intensity, other types of exercise or mileage. It is so common for even the experienced runner to fall foul of increasing weekly mileage incorrectly.
A group from Denmark designed a study with 874 runners. Each runner used a GPS watch to measure their distances and this was recorded over a 1 year period. The researchers found that novice runners were more likely to sustain a long distance running related injury e.g. Patello Femoral Joint Pain or Tendinopathy, if they increased there Weekly Mileage by more than 30%. Those who increased there Weekly Mileage by less than 10% were less likely to develop an injury.
Running Technique can also be an important part in staying pain free and running regularly.
Take home message: Do not increase your Weekly Mileage by more than 30%, try less than 10% per week, it may save you a lot of frustration.
