Greg McMillan is one of the most trusted coaches in the U.S. I’ve trained with him and been following him for 5+ years, so occasionally I’ll post one of his recent articles because they’re filled with nuggets that can help runners at all levels.
In the following article he identifies some of the most common mistakes made by runners at all levels. These mistakes typically lead to race outcomes that don’t meet expectations. These aren’t mistakes that often lead to injury.
The top mistake is very common with runners that aren’t being coached or coached properly. It involves lack of variety. You can’t do the same types of workouts at the same speed and expect to grow. For beginners there will be some improvement, but eventually the plateau will occur.
McMillan says that “with variety, we keep adapting to greater abilities.”
Another common mistake is too many races. Especially 1/2 and full marathons. I don’t have issue with racing, but if you’re actually racing them all, you’re likely to get worn down. This would certainly be the case if you’re running multiple 1/2 and full marathons throughout the year. Just like the variety of workouts is necessary, I strongly recommend a variety of races. Complete and train for 5 & 10k races to get faster. You’ll notice an improvement in your 1/2 and full marathon times.
