Challenge the 10% Rule: Safe Ways to increase Mileage
I’m always reading about running. I’m quite interested in learning about the sport. But, no matter where I look – Runner’s World, Running Times, Active.com – I see so-called “experts” recommending the 10% Rule. The 10% Rule essentially means that mileage should only be increased in 10% increments. So, if you run 30 miles this week and wish to increase your mileage, you should only run 3 additional miles to be “safe.”
