Strength work is rarely emphasized for most folks doing triathlons, marathons and ultras. It’s kind of an after thought that is low priority on the list of workouts. I’d like to redirect that focus though and share why strength work is the secret sauce that can propel your endurance fitness to new levels and extend your longevity in your sport.
If you are over about 35 years old, there is no amount of swimming, cycling or running that will keep the lean muscle on your that you garnered easily in earlier years. That is unless you do strength work.
A famous study done on marathon runners showed this. Over a 20 year period a group of runners who did the Boston Marathon were divided into two workout types. One group did pure running and no strength work. The other group did their normal marathon training but added in regular strength work. Each group was measured for the amount of their body that was lean muscle.
The runners who did not do strength training actually lost about 1% of their lean muscle each year over that 20-year research study. This is what is expected from the basic aging process for people in general.
The other group that did strength work actually maintained almost exactly the same amount of lean muscle that they had over the 20-years of the study. In other words, even though they were 20 years older at the end, they still had the same amount of muscle that they had at the beginning 20-years earlier.
Every joint in the body is held in place by muscle, tendons and ligaments. When we move all those elements work together to keep the joints working in alignment. If any of those areas weaken or don’t work right alignment fails and injury can happen. Something gets sore or inflamed. Having strong integrity of your muscles is a huge part of making sure that doesn’t happen. And strength work is a nearly perfect guarantee that the body will move as it should.
Muscle is also a very metabolically demanding tissue. It burns calories and requires a lot to repair and replenish it. It’s a great way to help regulate overall body weight since doing strength work increases the amount of lean muscle you have.
In long endurance events there is always going to be demands on your muscles that end up breaking them down. In fact, in blood analysis research done on athletes after they finish marathons and long triathlons, the muscle breakdown factors are similar to what is found in someone who just had a heart attack!
Of course you don’t have a heart attack in a race. But the message is that there is a lot of muscle being used in your endurance event. And when that takes place there is a part of your brain that is telling you to stop. Slow down. Call it a day. This is just part of sparing your body and survival. We override that call and keep going anyway. But the message here is this. Build more muscle through strength training and you will weather that slow down call much better.

I am the Founder and CEO at Mark Allen Coaching. I am proud to have been voted in an ESPN global poll "The Greatest Endurance Athlete Of All Time." During my multi-sport career I won the Ironman Triathlon World Championship six time, the inaugural Triathlon World Championship at the Olympic Distance in Avignon, France, and at one point in my career I won 21 straight races across every derivation and distance. It was a great career, but that's all it would ever be unless I was able to share all of the experience and methodology we invented long before smart watches, power meters, and flashy uniforms. That's why I started Mark Allen Coaching, as a way to return to others at least the part of the gifts I received.
