As the fall and winter marathon season starts heating up, and as the preparation for the spring marathons approaches, I feel appropriate to repost an article I wrote last year, that it is still relevant at this time of the running season. Enjoy!

 Tapering time approaches for those about to run the Abbott World Marathon Majors this year. Training time approaches for those eyeing their marathon towards the end of 2021 or start of 2022. So, seems like a good time to review some basic mistakes that runners, from beginners to experts, should avoid. This way they can reap the most benefits out of their efforts.

Training for a marathon is a process that involves multiple moving parts that need to work in sync. It needs to reach a point where the body can be stressed enough to compensate its deficiencies and adjust to the workload-thus improving- but not to a point where it becomes too much, and it can’t recover to do it again. This means overtraining and, most likely, an injury if intend to tough it out and train through it.

The following are nine of the most common mistakes runners incur into during a marathon training cycle:

1       Running the long runs too fast: There is a time to go fast and there is a time to go slow. The long run has that name because it is designed for you to go long. It is not called the “fast run” for a reason. They are intended to build up your aerobic system, which, for a marathon, it is used 99% of the time, even if you are the world-record holder.

 2       Focusing too much on the long run: The long run is an important part of your training, sure, but it is just one element, not the bulk of it. The success in your race will depend on the accumulated effect of all the elements in your training, not just one.

 3       Doing the same workouts all the time: Because about 80% of the training needs to be done at a slower speed, there is a small number of hard sessions available, usually no more than two per week, so distance, speed, intensity, and other parameters, need to be worked so the body can benefit and adapt.

 4       Poor fueling and hydration plans: if you don’t test strategies during training, you won’t know what works for you. The time to find that out is during training, long runs, especially. The time to realize a certain gel upsets your stomach, is not during the race. Same applies to hydration. What to drink and when needs to be part of race plan, shouldn’t be improvised on race day.

 5       Skipping rest days: Not running on a specific day is part of your training. These days should be written into your schedule and followed to the tee. No amount of ice baths, compression socks or protein shakes will do you any good if you don’t give your body a break to recover so it can run again.

Rest is as part of your training as your work. Don’t skip it!

6       Not scheduling cutback weeks:  During training you build up endurance, aerobic capacity, Vo2Max, and multiple additional parameters. But you can’t build up forever. Your body has a limit and needs time to actively rest so it can adapt to the benefits provided by your workouts. Programming a week to cut back on your training provides your body with time to adjust and recover, is key.

7       Cutting sleep:  Remember you don’t improve when you work out, you improve while you sleep. The long run the tempo, the weightlifting, or the speed session damage your body. It is when you sleep that your body gets repaired. If you skip on sleep, you won’t realize all the benefits of the training, but you will keep the muscle damage.

 8       Screwing up the tapering: Physiological adaptations after exercise, take between two and three weeks to adapt. So, there is no benefit on one last long run in the last couple of weeks. You need to actively rest and recover your body so it will be in its best shape for race day. During tapering there is nothing to gain, yet a lot to lose.

 9       Following someone else’s training plan: There is nothing wrong with talking to your buddies about what they are doing, but they may not have the same goals as you and you do not have the same physiology as them. Set up YOUR PLAN, adjust as needed, and stick to it. Trust your coach. Trust your plan. Trust yourself.

Of course, there are more than nine mistakes you can incur during a marathon training cycle. These are just some of the most common and they mostly apply to any distance. As you finish your training for your Abbott Marathon Major or get ready for your upcoming goal race, make sure you are on the lookout for the aforementioned mistakes, so you won’t screw up your hard work.
