Running: Avoiding Injuries & The 10% Rule

Listen to this Episode

This episode is brought to you by Star brite — Premium marine cleaning and maintenance for your boat.

Episode Show Notes

Avoiding running injuries comes down to two rules: never increase your weekly mileage more than about 10 percent, and stop doing the exact same run — same route, same speed, same direction — every single day. I am not an expert in running, but I am an expert in injuring myself. I went from not running at all to a 3:13 marathon, missing the Boston qualifier by three minutes, and I made every mistake along the way. In this Physical Friday I share the protocol that finally kept me healthy.

Frequently Asked Questions

What is the 10% rule in running?

The rule of thumb is to increase your weekly mileage by no more than about 10 percent per week. If you are running 10 miles this week, run 11 next week. Occasionally you might jump a little more, but the principle stands: build slowly. If you are aiming at a marathon program that peaks anywhere between 30 and 60 miles a week, it takes a long time to build there — you are essentially training for the training.

Why do new runners get injured so often?

Too much, too fast, too soon. Your cardiovascular system adapts quickly — you could run all day — but your tendons, ligaments, and cartilage are not ready for the pounding. The injuries usually hit right when you are loving running the most and want to do more, which makes it incredibly frustrating. Running takes more patience than almost any sport because your engine outpaces your chassis.

Why is running the same route every day a bad idea?

Picture a two-mile neighborhood loop out of your driveway, same distance, same speed, same direction, every day. The road has a slight grade, so one leg is always on the downhill side taking more wear. You are pounding concrete or asphalt — very hard surfaces — with identical stress patterns daily. That repetition with zero variation is one of the easiest ways to develop an overuse injury.

How should you vary your running to stay healthy?

Vary the distance, the speed, and the route. Some days go short and fast, some days long and slow, some days run sprints, and some days simply turn left out of the driveway instead of right. Take the same weekly mileage and break it up in different ways — one day a single mile, another day five, another day two miles very slow. Keep it different, and you will have a much better chance of increasing your mileage 10 percent a week without injury.

What running injuries are most common from overtraining?

I have had most of them. Iliotibial band syndrome, which feels like a knife jabbing into the side of your knee. Plantar fasciitis. Calf issues, knee problems, hip problems — nagging injuries that take a long time to get over. Almost all of mine came from jumping my mileage in huge percentages instead of building patiently. They were unnecessary, and yours can be too.

Can a beginner really build up to a marathon?

Yes — I am proof. I went from doing nothing but fishing to running more and more, set a goal to run a marathon, and eventually ran 3:13, missing the Boston qualification by three minutes. It stung then, but I am proud of it now because I came from a place of not being a runner at all. Build slowly, vary everything, follow a real program, and the distance will come.

How Running Turned My Physical Life Around

Running was the way I rebuilt myself physically. I went from nothing but fishing to chasing marathons, and the journey ended with a 3:13 — three minutes shy of Boston. Along the way I made every mistake a new runner can make, which is why when people ask if I know about running injuries, I tell them I have had them all and gotten over them all. The full story is in the episode, so press play in the player above.

Train for the Training

Here is the part nobody tells new marathoners: a standard program like Hal Higdon's peaks at serious weekly mileage, and there are newer programs with less volume, but either way you cannot jump straight into it. If the marathon is on the horizon, you need to train to be ready for the training. That mindset alone prevents most of the injuries that derail first-time marathoners. I get into the details in the episode — press play in the player above.

How to Build Running Mileage Without Getting Injured

This is the running protocol I lay out in the episode — the one I wish I had followed from the start.

  1. Follow the 10% rule. Increase weekly mileage no more than about 10 percent — 10 miles this week means 11 next week.
  2. Stop running the same loop. Same route, same speed, same direction every day concentrates wear on the same tissues, especially with a road's grade loading one leg.
  3. Vary the distance. One day run a single mile, another day five — spread your weekly miles unevenly instead of identically.
  4. Vary the speed. Mix short and fast days, long and slow days, and sprint days instead of one constant pace.
  5. Vary the route and surface. Turn left instead of right, find softer surfaces when you can, and give your body different stresses to adapt to.
  6. Be patient past the excitement. The danger zone is when you love running and want more — your heart is ready long before your tendons and ligaments are.

I walk through each of these in the episode. Press play in the player above.

Final Thoughts From Me

There are excellent running books and coaches out there far better than me — I am just relaying what I have read, what I have heard, and what has worked after doing it exactly wrong. Vary the distance, the route, and the speed, and increase the mileage slowly. If you are a prospective runner looking to get into the sport, that is my advice.
