Yasso 800s as Marathon Predictor

The Effectiveness of Yasso 800s as a Marathon Predictor

The marathon is a grueling race that tests the physical and mental limits of runners. It requires months of training, dedication, and careful planning. One aspect of marathon training that has gained popularity in recent years is the use of Yasso 800s as a predictor of marathon performance. Yasso 800s are a type of interval workout that involves running 800 meters at a specific pace, with equal recovery time in between. The theory behind using Yasso 800s as a marathon predictor is that the average time it takes to complete the 800-meter intervals can be used to estimate the time it will take to complete a marathon.

The idea of using Yasso 800s as a marathon predictor was first introduced by Bart Yasso, the Chief Running Officer at Runner’s World magazine. Yasso claimed that if a runner could consistently complete 10 repetitions of 800 meters in the same time it takes to run a marathon, then they would be well-prepared to run the marathon at that pace. For example, if a runner could consistently complete the 800-meter intervals in 3 minutes and 30 seconds, then they should be able to run a marathon in 3 hours and 30 minutes.

Many runners have embraced Yasso 800s as a marathon predictor and have found success in using this method to set realistic goals for their marathon races. However, it is important to note that Yasso 800s should not be the sole basis for determining marathon performance. There are many other factors that can affect marathon performance, such as weather conditions, course elevation, and individual fitness levels.

While Yasso 800s can provide a rough estimate of marathon performance, it is important to remember that they are just one tool in a runner’s training arsenal. It is still necessary to incorporate other types of workouts, such as long runs, tempo runs, and hill repeats, into a training plan in order to build endurance and improve overall performance.

Additionally, it is important to consider that Yasso 800s may not be suitable for all runners. Some runners may find that they do not respond well to this type of interval workout, or that it does not accurately predict their marathon performance. It is always best to consult with a coach or experienced runner before incorporating Yasso 800s into a training plan.

In conclusion, Yasso 800s can be a useful tool for estimating marathon performance, but they should not be relied upon as the sole predictor. They can provide a rough estimate of marathon time, but other factors such as weather conditions and individual fitness levels must also be taken into account. It is important to use Yasso 800s in conjunction with other types of workouts to build endurance and improve overall performance. Ultimately, the best way to predict marathon performance is through consistent training, careful planning, and listening to your body.
